HUAWEI CX600 Metro Service Platform Commissioning Guide
About This Document
About This Document Purpose This document is a guide to CX600 commissioning and verification. It describes how to commission hardware, links, services, and maintenance and management during deployment, ensuring stable and reliable operation of CX600 on networks. The intended audience of this document includes installation and commissioning engineers. NOTE
l This document takes interface numbers and link types of the CX600-X8 as an example. In working situations, the actual interface numbers and link types may be different from those used in this document. l In CX600 series (except for the CX600-X1/X2), line processing boards are called Line Processing Units (LPUs) and switching fabric boards are called Switching Fabric Units (SFUs). The CX600-X1/ X2 has no LPU and SFU, and packet switching and forwarding are centrally performed by the Network Processing Unit (NPU).
NOTICE Note the following precautions: l Currently, the device supports the AES and SHA2 encryption algorithms. AES is reversible, while SHA2 is irreversible. A protocol interworking password must be reversible, and a local administrator password must be irreversible. l If the plain parameter is specified, the password will be saved in plaintext in the configuration file, which has a high security risk. Therefore, specifying the cipher parameter is recommended. To further improve device security, periodically change the password. l Do not set both the start and end characters of a password to "%$%$." This causes the password to be displayed directly in the configuration file.

Check that network connections are proper. Run the ping command on the client to check network connections. If ping results are negative, network connections are faulty and Telnet connections cannot be set up. Check whether unstable connections that cause packet loss or occasional login failures exist in the network. If network connections are faulty, follow the procedure described in "The Ping Operation Fails" in the HUAWEI CX600 Metro Services Platform Troubleshooting to locate and rectify the fault and ensure that the Telnet client can successfully ping the Telnet server.
2.
Check whether login users on the CX600 have reached the maximum. Log in to the CX600 by using the console interface. Then, run the display users command to check whether the VTY user interfaces are all used. By default, a maximum of five VTY user interfaces are available to login users. You can run the display user-interface maximum-vty command to view the allowed maximum number of login users. display user-interface maximum-vty Maximum of VTY user:5 display users User-Intf Delay Type Network Address 34 VTY 0 03:31:35 TEL 10.138.81.138 Username : Unspecified 35 VTY 1 03:51:58 TEL 10.137.128.126 Username : Unspecified 36 VTY 2 00:10:14 TEL 10.138.81.184 Username : Unspecified 37 VTY 3 02:31:58 TEL 10.138.80.199 Username : Unspecified + 38 VTY 4 00:00:00 TEL 10.138.78.80 Username : Unspecified

If an ACL is configured but the IP address of a client from which the access is permitted is not specified in ACL rules, the client cannot telnet to the CX600. This means that to allow a client to telnet to the CX600, you must specify the IP address of the client in the permit rule of the ACL bound to VTY user interfaces. 4.
Check that the access protocol has been correctly configured in the VTY user interface view. [HUAWEI] user-interface vty 0 4 [HUAWEI-ui-vty0-4] display this user-interface vty 0 4 authentication-mode aaa user privilege level 3 idle-timeout 0 0 protocol inbound ssh

The protocol inbound { all | ssh | telnet } command is used to specify protocols supported by the current user interface. telnet is the default parameter. If ssh is specified, Telnet login is prohibited. If all is specified, both Telnet login and SSH login are allowed. 5.
Check whether extended VTY user interfaces 16 to 20 are available to login users. These user interfaces are reserved for NMS users. Whether VTY user interfaces 0 to 14 are all used, VTY user interfaces 16 to 20 are open to NMS users (whose user type is netmanager) only, not common login users. The display users command can be used to check the user login information of every VTY user interface.
6.
Check that a password has been set in the user interface view. If the authentication-mode password command has been run in the VTY user interface view to set the authentication mode to password, the set authentication password command must be run to set an authentication password. The authentication mode can also be set to aaa by running the authentication-mode aaa command.
7.
Check that the user level is correct. If the authentication mode in the VTY user interface view is set to password or none, you need to check the user level. Low-level users, after login, are not allowed to run high-level commands such as the system-view command. If you use an administrator account to log in to the CX600, you can run the user privilege level level command to configure the level of commands that the user logging in through the current user interface can use. NOTE
By default, command levels are 0, 1, 2, and 3. Before the upgrade of command levels, user levels 3 to 15 are the same, which are all management levels.

After an upgrade, if the original key pair length is shorter than 1024 bits, running the rsa local-key-pair create command to generate a new local key pair is recommended. l After a local key pair is generated, you can run the display rsa local-key-pair public command to view the public key in the local key pair. l To clear the local RSA key pair, run the rsa local-key-pair destroy command to destroy all local RSA key-pairs, including the local key-pair and server key-pair. Check whether all local RSA key pairs are destroyed after running the rsa local-key-pair destroy command. The rsa local-key-pair destroy command configuration takes effect only once and therefore will not be saved in the configuration file.
l Run the dsa local-key-pair create command to generate the RSA local-key-pair. NOTE
l You must configure the dsa local-key-pair create command to generate a local key pair before completing other SSH configurations. The length of the server key pair and the host key pair can be 512 bits, 1024 bits and 2048 bits. By default, the length of the key pair is 2048 bits. l After a local key pair is generated, you can run the display dsa local-key-pair public command to view the public key in the local key pair. l To clear the local DSA key pair, run the dsa local-key-pair destroy command to destroy all local DSA key-pairs, including the local key-pair and server key-pair. Check whether all local DSA key pairs are destroyed after running the dsa local-key-pair destroy command. The dsa local-key-pair destroy command configuration takes effect only once and therefore will not be saved in the configuration file.
l Run the ecc local-key-pair create command to generate the ECC local-key-pair. NOTE
l You must configure the ecc local-key-pair create command to generate a local key pair before completing other SSH configurations. The length of the server key pair and the host key pair can be 256 bits, 384 bits and 521 bits. By default, the length of the key pair is 521 bits. l After a local key pair is generated, you can run the display ecc local-key-pair public command to view the public key in the local key pair. l To clear the local ECC key pair, run the display ecc local-key-pair public command to destroy all local ECC key-pairs, including the local key-pair and server key-pair. Check whether all local ECC key pairs are destroyed after running the ecc local-key-pair destroy command. The ecc local-key-pair destroy command configuration takes effect only once and therefore will not be saved in the configuration file.
Method 2: 1.
Run the rsa key-pair label, dsa key-pair label, or ecc key-pair label command in the system view to create an RSA, DSA, or ECC key pair.
2.
Run the ssh server assign { rsa-host-key | rsa-server-key | dsa-host-key | ecc-hostkey } key-name command in the system view to assign an RSA host key, RSA server key, DSA host key, or ECC host key to an SSH server.
After the key pair is generated, run the display rsa key-pair, display dsa key-pair, or display ecc key-pair command to check information about the RSA, DSA, or ECC key pair. Issue 04 (2014-04-01)

Description
Configure Password Authentication
1. Run the ssh user user-name authentication-type password command
If local or HuaWei Terminal Access Controller Access Control System (HWTACACS) authentication is used and there are only a few users, use password authentication.
2. Run the aaa command to enter the AAA view.
-
3. Run the local-user user-name password { cipher | irreversiblecipher } password command to configure the username and the password for the local user.
The username must be the same to the SSH user.
4. Run the local-user user-name service-type ssh command to set the access type of the local user to SSH.
-
Configure the Default Password Authentication
Run the ssh authentication-type default password command
When you log in using SSH and use a TACACS server for authentication, the network administrator needs to specify the information about an SSH user on the TACACS server. In most cases, however, the SSH server cannot obtain the user information from the TACACS server. To resolve this problem, you can run the ssh authentication-type default password command to set the authentication mode as password authentication. Then, you can log in to the device on the SSH server safely.
Configure RSA authentication
1. Run the ssh user user-name authentication-type rsa command to configure RSA authentication.

Description
2. Run the rsa peer-public-key keyname [ encoding-type { der | openssh | pem } ] command to configure an encoding format for an RSA public key and enter the RSA public key view.
Huawei data communications devices support only the DER format for RSA keys before V600R006C00 version. If you use an RSA key in non-DER format, use a third-party tool to convert the key into a key in DER format.
The default encoding format is distinguished encoding rules (DER) for an RSA public key.
Because a third-party tool is not released with Huawei system software, RSA usability is unsatisfactory. In addition to DER, RSA keys need to support the privacy-enhanced mail (PEM) and OpenSSH formats to improve RSA usability after V600R006C00 version. Third-party software, such as SecureCRT, PuTTY, OpenSSH, and OpenSSL, can be used to generate RSA keys in different formats. The details are as follows: l The SecureCRT and PuTTY generate RSA keys in PEM format. l The OpenSSH generates RSA keys in OpenSSH format. l The OpenSSL generates RSA keys in DER format.
3. Run the public-key-code begin command to enter the public key edit view.
-
4. Enter hex-data to edit the public key.
l In the public key edit view, only hexadecimal strings complying with the public key format can be typed in. Each string is randomly generated on an SSH client. For detailed operations, see manuals for SSH client software. l After entering the public key edit view, paste the RSA public key generated on the client to the server.

Prerequisite l
Connecting the remote device with empty configuration to a local device directly
l
Making sure that the interfaces connecting the remote device with empty configuration to the local device are Up and support NAP NOTE
If the IP addresses used for establishing NAP connections need to be configured, you need the IP addresses of the master and slave interfaces (the IP addresses must be on the same network segment) before configuring NAP. If the IP addresses for establishing NAP connections are automatically allocated, you do not need any data. Perform the following configurations on the CX device where a NAP function needs to be configured and started.
NOTICE If commands (such as commands related to the VPN, Eth-Trunk, IP-Trunk, or Layer 2 interface) affecting IP address configuration or IP packet forwarding have been run on the NAP master interface, the NAP function will not take effect. In this case, delete these commands and reenable NAP. The IP address of a NAP master interface can be configured or automatically allocated by the system. After the local interface is specified as the NAP master interface, NAP automatically allocates IP addresses from the default address pool 10.167.253.0/24 to the master and slave interfaces. If the address conflict, manually configure addresses for them. There are two configuration modes: to specify a NAP IP address pool, IP addresses from which will be automatically allocated based on a NAP address allocation algorithm, or to configure IP addresses of the same network segment for the master and slave interfaces.
Procedure Step 1 Allocate the IP addresses l

Log in to the NAP slave device from the NAP master device. l If the slave device does not have any configuration, you can log in to the slave device from the master device with having to input a user name and a password. l If a user name and a password have been configured on the slave device, you must input the user name and password to log in to the slave device. NOTE
The passwords must meet the following requirements: l The password is a string of 8 to 16 case-sensitive characters. l The password must contain at least two of the following characters: upper-case characters, lower-case characters, numbers, and special characters (excluding question marks and spaces).
After the user name and password are configured for the slave device, NAP will be automatically disabled if the device is restarted. NOTE
The slave device with empty configurations checks the Telnet source address of the Telnet login. If the Telnet source address is the NAP address of the master device, the slave device will require a user to enter the password for login authentication. This is because the user level of the remote login using the NAP address is the same as that (the highest user level) of the login using a console interface.
Step 3 Disabling NAP on the Slave Device 1.
Run: system-view
The system view is displayed. 2.
Run: undo nap slave enable
NAP is disabled on the slave device. ----End

Troubleshooting l
If the physical status of an Ethernet interface is Down after the interface is configured, perform the following operations: 1.
Check that the peer device is started. If the peer device is not started, start it.
2.
Run the display interface interface-type interface-number command to view the optical module information and interface configurations on the local and peer ends. – Check that the optical modules on the local and peer interfaces are matched, including interface types, rate, wavelengths, and optical powers of optical modules. Check the fiber connected the optical modules and the power of connected optical modules meet the requirement. If the fiber or either of the optical modules does not meet the requirement, replace it. – Check that the auto-negotiation modes on the local and peer interfaces are consistent. If they are inconsistent, run the duplex command to make the two interfaces use the same duplex mode.

– Check that the interface configurations such as the MTU, TTL of packets, format of transmitted Ethernet frames, and maximum QoS bandwidth on the local and peer ends are consistent. If they are inconsistent, adjust them to ensure consistency. – Check that the traffic is normal. 3.
Check that the fiber is properly and correctly installed. This means that the fiber is connected to the correct transmit optical module and receive optical module.
4.
Perform self-loop detection on interfaces to check whether the interfaces are normal. After you run the undo shutdown command in the interface view, connect the RX end and TX end of an optical module on the local interface using a fiber. Check whether the interface is Up. If the interface is Up, the local interface is normal. Perform the same operation on the remote interface. If the remote physical layer is Up, the remote interface is normal. You need to replace the fiber.
5. l
If the fault persists after the preceding operations are complete, contact Huawei technical support personnel.
If an Ethernet interface cannot be pinged, perform the following operations: 1.
Check that the local end is correctly connected to the peer end. Observe the Link indicator on the LPU where the local Ethernet interface resides. If the indicator is on, the link works properly. If the indicator is off, check the optical module, interface, fiber, and the device.
2.
Check that the auto-negotiation modes on the local and peer Ethernet interfaces are consistent.
3.
Check that the IP address of the local Ethernet interface belongs to the same subnet as that of the peer Ethernet interface. This means that the two IP addresses must have the same network address and different host addresses. If the two IP addresses do not belong to the same subnet, reconfigure the IP addresses.
4.
Check that the link layer protocols on the local and peer ends are consistent. Reliable communication between two Ethernet devices is available only when they use the same link layer protocol.
5.
If the fault persists after the preceding operations are complete, contact Huawei technical support personnel.

If the alarm count and error count are not 0, run the command several times to check whether the counts increase. Or, run the reset counters interface command to clear the statistics and then run the command several times. Step 3 Run the ping command to test POS link connectivity. For example: ping 192.168.1.2 PING 192.168.1.2: 56 data bytes, press CTRL_C to break Reply from 192.168.1.2: bytes=56 Sequence=1 ttl=255 time=2 ms Reply from 192.168.1.2: bytes=56 Sequence=2 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=3 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=4 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=5 ttl=255 time=113 ms --- 192.168.1.2 ping statistics --5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 1/23/113 ms
In normal situations, the ping operation should succeed. ----End
Troubleshooting If the physical status of a POS interface does not go Up after it is connected, perform the following operations: 1.
Check that the local and peer POS interfaces are enabled, the input and output optical power of the interfaces are normal, and there are no SDH alarms. Run the display interface pos [ interface-number ] command. l If the value of the current state field is Administratively down, the POS interface is not enabled. Run the undo shutdown command in the interface view. l If the output optical power is not within the allowed range, replace the optical module. l If the input optical power is smaller than the receiver sensitivity, adjust the link or replace the peer optical module. l If the values of the fields under the SDH alarm field are not none and B1, B2, and B3 error code counts displayed under the SDH error fields increase, note the following points: – If B1, B2, and B3 error code counts all increase, check the direct link between the optical modules as well as these modules on the two ends. If the link is a WDM link, ensure that it is stable. – If only the B3 error code count increases, check the link directly connecting the peer device and an SDH device because this problem often occurs when a routing device is connected to an SDH device. If the link between the concerned SDH devices is a WDM link, you also need to check the entire WDM link to ensure stable transmission. If the fault persists, go to Step 2.
2.
Check that the fiber and optical modules are properly installed. An optical module or a fiber connector has a fastener. If you hear a click when installing the fiber or an optical module, the fiber or optical module is properly installed. If the fault persists, go to Step 3.

Check that the fiber is connected to the correct transmit optical module and receive optical module. Remove the fiber and connect it to a different module of the original interface on each end (for example, if the fiber is connected to the transmit optical module of an interface on the local end, remove it and then connect the fiber to the receive optical module of that interface on the local end). If the fault is not rectified, restore the original fiber connection. If the fault persists, go to Step 4.
4.
Use a fiber to perform local loopback. Use a good fiber to connect the transmit and receive optical modules of the local interface. l If the physical layer is Up and SDH alarms are all cleared and B1, B2, and B3 error code counts do not increase on the interface, the local optical modules and the board where the interface resides work properly. You need to check the link and the peer device. l If the physical layer is not Up, the local optical modules or the board where the modules reside works abnormally. Switch the services of the board or the concerned interface to another board and then replace the optical modules or the board to see if the fault will be rectified. NOTE
Before using a fiber to perform local loopback, run the clock master command to set the clock mode of an interface to master.
If the fault persists, go to Step 5. 5.
Collect the following information and contact Huawei technical support personnel: l Results of the preceding operation procedure l Configuration files, log files, and alarm files of the CX600

As shown by the characters displayed in boldface, the CPOS interface status is UP when the CPOS interface is correctly configured, and no alarms or errors are displayed. If the alarm count and error count are not 0, run the command several times to check whether the counts increase. Or, clear the statistics and then run the command several times. Step 2 Run the display interface serial command to view the operating status of and statistics on the serial interface. For example: display interface serial 1/0/0/0:0 Serial1/0/0/0:0 current state : Up Line protocol current state : Up Description:HUAWEI, Quidway Series, Serial1/0/0/0:0 Interface Route Port,The Maximum Transmit Unit is 1500, Hold timer is 10(sec) Derived from CPOS 1/0/0 e1 1, Timeslot(s) Used: 1-31, baudrate is 1984000 bps Internet protocol processing : enabled Link layer protocol is PPP LCP initial clock master, loopback none CRC: CRC-32 Current system time: 2011-01-21 17:45:40 Framer LOS Alarm Status(0-NONE 1-ALARM): 0 Framer LOF Alarm Status(0-NONE 1-ALARM): 1 Framer PAIS Alarm Status(0-NONE 1-ALARM): 1 Framer PRDI Alarm Status(0-NONE 1-ALARM): 0 PSN2TDM PW Alarm status(0-NONE 1-RDI 2-AIS): 0 Statistics last cleared:2011-01-21 10:18:07 09:25:21 Traffic statistics: Input: 0 packets Output: 0 packets Output error: 0 underrun count, 0 overrun count 0 misorder packets, 0 malformed packets 0 los packets, 0 dummy packets ES: 0, SES: 0, UAS: 0 Input bandwidth utilization : 0.00% Output bandwidth utilization : 0.00%
As shown by the characters displayed in boldface, the physical status and link layer protocol status of the serial interface are Up when the serial interface channelized from a CPOS interface is correctly configured. If the IP addresses of the serial interfaces on both ends of the link and routes are correctly configured, the network layer protocol status on the local serial interface is enabled. Step 3 Run the ping command to test CPOS link connectivity. For example: ping 192.168.1.2 PING 192.168.1.2: 56 data bytes, press CTRL_C to break Reply from 192.168.1.2: bytes=56 Sequence=1 ttl=255 time=2 ms Reply from 192.168.1.2: bytes=56 Sequence=2 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=3 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=4 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=5 ttl=255 time=113 ms

In normal situations, the ping operation should succeed. ----End
Troubleshooting If serial interfaces on the two ends of a link cannot communicate with each other after the interfaces are configured, perform the following operations: 1.
2.
Check the physical status of the CPOS interfaces on both ends. a.
Check the type of fiber connecting the CPOS interfaces and whether the fiber is correctly installed.
b.
If the fiber is correctly and properly installed, run the undo shutdown command and then the display this interface command on the local serial interface. You can see that the physical status of the interface is Up.
c.
If the physical status of the interface is Down, run the clock master command and then the loopback local command on the CPOS interface on each end. If the physical status of the interface on each end is Up, the fiber may be faulty. If the physical status of the interface on either end is still Down, the board where the interface resides may be faulty. In this case, seek technical support.
Check that the link layer protocol configurations on both ends of the link are consistent. a.
Run the display this interface command on the serial interface on each end to view the configured link layer protocol. If PPP is configured on one end and HDLC is configured on the other end, change the link layer protocol configurations to ensure consistency on both ends.
b.
Check whether the MTUs on the serial interfaces on both ends are the same. Run the display interface interface-type interface-number command on the serial interface on each end to view the MTU. If the MTUs on the serial interfaces on the two ends are not the same, run the mtu command on one end to ensure MTU consistency.
If the fault persists, proceed with the following operations. If the link layer protocol is HDLC, go to Step 3. If the link layer protocol is PPP, go to Step 4. 3.
Check that the HDLC configuration is correct. a.
Check whether IP address unnumbered is configured on the serial interfaces on both ends. Run the display this command on the serial interface on each end to check whether the ip address unnumbered interface interface-type interface-number command has been configured. If that command has been configured, ensure that the IP address borrower can learn the route to its peer. Otherwise, the ping operation will fail.
b.
Check whether the same hold time is configured on the two ends. Run the display interface interface-type interface-number command on the serial interface on each end to view the value of the hold timer field. If different values of

5 Commissioning the Link Layer
the hold timer field are configured on the two ends, run the timer hold command on one end to change the field value and ensure value consistency. If the fault persists, contact Huawei technical support personnel. 4.
Check that PPP works properly between the serial interfaces on the two ends. Verify that IP addresses are correctly configured for the serial interfaces on the two ends. Then, run the display this interface command on the serial interface on each end. If the command output shows that the link layer protocol is Down, perform the following operations to find the reason why PPP is not started: a.
Check whether Link Control Protocol (LCP) negotiation goes smoothly. LCP negotiation is the first phase of the setup of a PPP connection. If LCP negotiation between the two ends succeeds, a link will be set up and some basic link characteristics on the two ends will reach consistency. Run the display this interface command on the serial interface on either end. The command output shows the LCP negotiation status. If the status is opened, LCP negotiation is completed. Otherwise, LCP negotiation has not been completed yet.
b.
Check whether Internet Protocol Control Protocol (IPCP) negotiation goes smoothly. IPCP negotiation follows successful LCP negotiation and authentication. In this phase, the IP addresses of serial interfaces are negotiated between the two ends. As a prerequisite, the serial interfaces on the two ends must be configured with IP addresses. Otherwise, the IPCP negotiation status cannot be checked. After confirming that the IP addresses configured on the serial interfaces on the two ends are correct, run the display this interface command on the serial interface on either end. The command output shows the IPCP negotiation status. If the status is opened, IPCP negotiation is completed. Otherwise, IPCP negotiation has not been completed yet.
5.
Check statistics on the serial interfaces on the two ends. If PPP is started after LCP and IPCP negotiation but the serial interfaces on the two ends still cannot ping each other, check statistics on the serial interfaces to find if the transmission of other types of packets is faulty. NOTE
Authentication is required between LCP negotiation and IPCP negotiation, which can be Password Authentication Protocol (PAP) authentication or Challenge Handshake Authentication Protocol (CHAP) authentication. If authentication fails, the link is disconnected. It is supposed that no authentication is configured in the preceding steps. If authentication is configured in real-world situations, check that the user name and password of the authenticated are correct. In addition, to check that the authentication messages are correctly transmitted and received, enable debugging and check the statistics on the interface.
6.
If the fault persists, contact Huawei technical support personnel.
5.4 Checking E-Carrier and T-Carrier Interfaces This section describes how to check the link layer on E-Carrier and T-Carrier interfaces. In this section, a CE1 interface is used as an example.

Troubleshooting If E-carrier or T-carrier interfaces on both ends of a link cannot communicate with each other after the interfaces are configured, perform the following operations: 1.
Check that the physical layer is Up. a.
Run the display controller e1 command to view interface information on each end. If the physical status is displayed as Administratively Down, the shutdown command has been run on the interface. Run the undo shutdown command to enable the interface. If the physical status is displayed as Down, check the following items: l Fiber is properly connected to the local interface and the indicator for the interface is in a normal state. l Fiber is properly connected to the peer interface. Run the display this interface command in the interface view to check if the physical status of the peer interface is Administratively Down and if loopback is configured on the peer interface. l Interface configurations, such as the operation mode and line coding/decoding format, on the two ends are consistent, and the clock modes configured on the two ends are correct.
b.
If the fault persists, run the link-protocol command in the CE1, serial, CT1, E3, or CT3 interface view to set the link layer protocol to HDLC and then run the loopback command in the CE1, CT1, E3, or CT3 interface view. If the physical status of the interface is Up, the hardware on the local end works properly. The problem lies in the cable, and you need to replace the cable. If the physical status of the interface is Down, the board where the interface resides is faulty. The board needs to be repaired.
2.
Check that the link layer is Up. If the link status is Down, run the display interface serial command on each end to check the link status.
Issue 04 (2014-04-01)
a.
Check whether the two ends use the same link layer protocol. The link layer can go Up only when the two ends of the link use the same link layer protocol.
b.
If the physical layer is Up, check whether correct IP addresses are configured for the interfaces on the two ends.
c.
If the LCP negotiation status is not opened, LCP negotiation has not been completed yet. LCP negotiation is completed only when the LCP negotiation status is opened. Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd.

As shown by the characters displayed in boldface, the physical status and link layer protocol status of the ATM interface are UP when the ATM interface is correctly configured. The command output also displays the frame format, clock mode, statistics interval, and whether scrambling is enabled. Step 2 Run the display atm map-info command to check whether information in the upper layer protocol mapping table is correct. display atm map-info Atm1/0/0, PVC 1/33, IP, State UP100.11.1.1, vlink 1 Atm1/0/0, PVC 2/101, ETH, Virtual-Ethernet1/0/0, UP
Step 3 Run the display atm pvc-info command to view PVC information. display atm pvc-info VPI/VCI |STATE|PVC-NAME |INDEX |ENCAP|PROT |INTERFACE --------|-----|----------------|--------|-----|-----|------------------0/40 |UP | |1 |SNAP |IP |Atm1/0/0 (UP) 0/60 |UP |to_adsl_a |2 |SNAP |ETH |Atm1/0/0.1 (UP) VPI/VCI |STATE|PVC-NAME |INDEX |ENCAP|PROT |INTERFACE --------|-----|----------------|--------|-----|-----|------------------1/10 |UP | |2 |SNAP |None |Atm2/0/0.1 (UP) 1/100 |UP | |1 |SNAP |IP |Atm2/0/0 (UP)
Check the boldfaced fields displayed in the preceding information to see if the PVC status is Up, the application mode is correct (in the PROT field, IP indicates IPoA, and ETH indicates IPoEoA), and the interface where the PVC resides is Up. Step 4 Run the display atm pvp-info command to view PVP information. display atm pvp-info VPI | STATE | PVP-NAME | INDEX | ENCAP | PORT | INTERFACE -------------------------------------------------------------------10 | UP | | 0 | AAL0 | None | Atm2/0/0.1(UP)
Check the fields displayed in boldface in the preceding information to see if the PVP status is Up, the application mode is correct (in the PROT field, IP indicates IPoA, and ETH indicates IPoEoA), and the interface where the PVP resides is Up. Step 5 Run the ping command to test ATM link connectivity. For example: ping 192.168.1.2 PING 192.168.1.2: 56 data bytes, press CTRL_C to break Reply from 192.168.1.2: bytes=56 Sequence=1 ttl=255 time=2 ms Reply from 192.168.1.2: bytes=56 Sequence=2 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=3 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=4 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=5 ttl=255 time=113 ms --- 192.168.1.2 ping statistics --5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 1/23/113 ms
In normal situations, the ping operation should succeed. ----End

Troubleshooting If ATM interfaces on the two ends of a link cannot communicate with each other after the interfaces are configured, perform the following operations: 1.
Enter the ATM interface view and run the display this interface command to check the physical status and link layer protocol status of the ATM interface on each end. If both statuses are Down, go to Step 2. If they are Up, go to Step 3.
2.
Check the physical status, link layer protocol status, and clock mode on the ATM interface on each end. l Check that fiber is correctly connected to the ATM interface. An ATM interface is connected to two fibers. One is used for signal receiving and connected to the receive optical module, and the other is used for signal transmission and connected to the transmit optical module. Ensure that the fiber connections are correct. If the fiber connections are incorrect, the physical status of the ATM interface is Down. If the fiber connections are correct, the Link indicator on the ATM interface is On. l The fiber connected to an ATM interface can be multimode or single-mode fiber. If some ping packets are lost or the ping fails, check whether the ATM interfaces on the two ends are multimode or single-mode interfaces. In most cases, a multimode interface and a single-mode interface that are directly connected can communicate with each other, but sometimes a great number of packets will be discarded or CRC errors will occur. l If two CX600s are directly connected, check whether the internal clocks are not enabled on two ATM interfaces. By default, one CX600 uses a line clock. If the CX600s are directly connected or connected through a WDM device, run the clock master command on one of the CX600s to provide an internal clock. l If the physical status of the interface remains Down, contact Huawei technical support personnel.
3.
Check that the PVCs on the interfaces on both ends are the same. Since ATM interfaces use PVCs for communication, the PVCs on the interfaces on both ends must be the same. For IPoA, check that the protocol address mapping is correctly configured. If two CX600s are directly connected, the PVC mapped from the local to the peer IP address must be the same as the PVC mapped from the peer to the local IP address. Check whether the authentication configurations on both ends are the same for PPPoA.
4.
Check that the configurations and protocol types on the ATM interfaces on the two ends are the same. Check that the protocols (IPoA, PPPoA, IPoEoA, or PPPoEoA) over the PVCs on the ATM interfaces on the two ends are the same. If the routing protocol over ATM is Open Shortest Path First (OSPF), the mapping information configured on the ATM interfaces must contain broadcast. If the ATM interfaces on the two ends can use short packets, but not long packets, to ping each other, check whether the MTUs on the ATM interfaces are the same.
5.
If the ATM interfaces on the two ends still cannot communicate with each other, contact Huawei technical support personnel.

Prerequisites l
Hardware installation is complete. For more information, see 4 Checking the Hardware.
l
The CX600 is running properly.
Procedure Step 1 Run the display fr interface command to view the physical status and link layer protocol status of FR interfaces and whether the FR interfaces are DTE or DCE interfaces. The command output also includes the type and link layer protocol status of the sub-interface. display fr interface Pos1/0/0, DCE, physical up, protocol up Pos1/0/0.1, point-to-point, protocol up
Check the information displayed in boldface in the preceding information to ensure that: l The working mode of the FR interface is correct. DTE indicates the working mode of the interface on the user side; DCE indicates the working mode of the interface on the network side. l The physical status and link layer protocol status are Up. l The network layer protocol is Up. l The sub-interface type is point-to-point. Step 2 Run the display fr map-info command to check the FR address mapping table. display fr map-info Map Statistics for interface Pos1/0/0 (DCE) DLCI 20, Point-to-Point DLCI, Pos1/0/0.1 created at: 2010/02/12 11:17:37, status: ACTIVE
Check the information displayed in boldface in the preceding information to ensure that the configured Data-Link Connection Identifier (DLCI) is correct and dynamic address mapping works properly (ACTIVE). Step 3 Run the ping command to test FR link connectivity. For example: ping 192.168.1.2 PING 192.168.1.2: 56 data bytes, press CTRL_C to break Reply from 192.168.1.2: bytes=56 Sequence=1 ttl=255 time=2 ms Reply from 192.168.1.2: bytes=56 Sequence=2 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=3 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=4 ttl=255 time=1 ms Reply from 192.168.1.2: bytes=56 Sequence=5 ttl=255 time=113 ms --- 192.168.1.2 ping statistics --5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 1/23/113 ms
In normal situations, the ping operation should succeed. ----End
Troubleshooting If the physical status of an FR interface is Down, check whether the interface is properly connected to a cable. If the network layer protocol status is Down, check whether no DLCI is Issue 04 (2014-04-01)

configured on the FR interface or its peer interface or the DLCIs configured on both ends are not the same. After changing the link layer configuration of an FR interface, run the shutdown command and then the undo shutdown command to restart the interface and make the configuration take effect. When configuring a DLCI on a sub-interface, you must shut down the sub-interface, configure a DLCI on the sub-interface, and then restart the sub-interface to make the configuration take effect.
5.7 Checking the Optical Power of Interfaces This section describes how to verify whether the optical power of SFP optical modules meets requirements. You need to check whether the optical power of SFP optical modules meets requirements. If the output optical power of SFP optical modules on the boards of the NE80E/40E does not meet requirements, packets will be lost and communication will be interrupted on the network layer.
Prerequisite l
Hardware installation is complete. For more information, see 4 Checking the Hardware.
l
The CX600 is running properly.
Procedure Step 1 Run the display interface interface-type interface-number command to view the operating status and statistics on each of two connected interfaces. Go on with the subsequent commissioning, if the maximum transmission distance and central wavelength of the optical modules on the two connected interfaces are consistent and the input optical power and output optical power of the optical modules are within the allowed range. In the following example, the display on a GE interface is used. NOTE
The display this interface command can also be run in the interface view to display interface information.

See "List of LPU Interface Attributes" in the appendix. To use the optical module on the local end, the following two conditions for the input optical power of the optical module must be met: l The input optical power must be greater than the receiver sensitivity of the optical module (3dBm). Otherwise, the peer end will not receive any signals. l The input optical power must be lower than the overload optical power (3dBm). Otherwise, the optical module may be damaged.
----End
Troubleshooting If the output optical power of an optical module is beyond the allowed range, replace the optical module.

Troubleshooting If static routes are correctly configured but the commissioning device fails to receive some or all routes, complete the following: 1.
Check that static route parameters are correctly configured. Run the display current-configuration | include route-static command to check whether static route parameters are correct and destination addresses, outbound interfaces, and next hops of IPv4 static routes are configured.
2.
Check that the precedence of static routes is correctly configured. Run the display ip routing-table command to check the precedence of static routes in the IPv4 routing table. The precedence of static routes is 60 by default, being lower than OSPF routes (10) and IS-IS routes (15). Therefore, if OSPF or IS-IS is also configured, to make static routes take effect, run the ip route-static default-preference preference command to set the default precedence of static routes to be higher than that of OSPF routes or IS-IS routes before configuring static routes. The smaller the preference value, the higher the preference.

Step 3 CX-B and CX-C synchronize the time with their own master devices. Run the display ptp utc command on CX-A, CX-B, and CX-C to check the UTC time. The command output shows that the UTC time synchronization on CX-A, CX-B, and CX-C reaches accuracy in seconds. [CX-A] display ptp utc UTC Time:2012-01-01 14:53:26 [CX-B] display ptp utc UTC Time:2012-01-01 14:53:26 [CX-C] display ptp utc UTC Time:2012-01-01 14:53:26
Run the display ptp all command on CX-B three to five times at an interval of several seconds and check whether the Realtime(T2-T1) field value remains at a fixed value. If so, CX-B has synchronized the time with CX-A. Repeat the preceding operation on CX-C and check whether CX-C synchronizes the time with CX-B. Issue 04 (2014-04-01)

Procedure Step 1 Run the display ospf peer command on the commissioning device to view its OSPF neighbor information. display ospf peer OSPF Process 1 with Router ID 1.1.1.1 Neighbors Area 0.0.0.0 interface 192.168.1.1(GigabitEthernet1/0/0)'s neighbors Router ID: 2.2.2.2 Address: 192.168.1.2 State: Full Mode:Nbr is Slave Priority: 1 DR: 192.168.1.1 BDR: 192.168.1.2 MTU: 0 Dead timer due in 35 sec Retrans timer interval: 5 Neighbor is up for 00:00:05 Authentication Sequence: [ 0 ]
The boldfaced items in the command output show the OSPF neighbor information. Then check the number of neighbors, whether or not the neighbor relationships are in the Full state (indicating that the neighbors have finished LSDB synchronization and established the Full adjacency) and whether or not the neighbors can remain in the Up state for a long time. If a neighbor stays in the Up state for a short period of time, the OSPF neighbor relationship has been recently interrupted. Pay attention to such a symptom. Step 2 Run the display ospf routing command on the commissioning device to view information about the OSPF routing table. Intra-area OSPF routes: display ospf routing OSPF Process 1 with Router ID 1.1.1.1 Routing Tables Routing for Network Destination Cost Type NextHop 192.168.1.0/24 1 transit 192.168.1.1 2.2.2.2/32 1 Stub 192.168.1.2 192.167.1.0/24 2 Stub 192.168.1.2 Total Nets: 3 Intra Area: 3 Inter Area: 0 ASE: 0 NSSA: 0

If the commissioning device has learned routes from other areas using OSPF, the routing table will contain them. The boldfaced items in the command output show that there are two intraarea routes, one inter-area route, and two AS external routes. Step 3 Run the display ospf interface command on the commissioning device to view its OSPF interface information. display ospf interface OSPF Process 1 with Router ID 1.1.1.1 Interfaces Area: 0.0.0.0 IP Address 1.1.1.1 192.168.1.1

The boldfaced items in the command output show the OSPF interface information. Check that the type, state, and cost of the OSPF-enabled interface are correct. Step 4 Run the display current-configuration command on the commissioning device to check the configurations that have taken effect. display current-configuration # ospf 1 vpn-instance comm_signal default-route-advertise always cost 1024 type 2 import-route direct import-route static route-tag 100 area 0.0.0.0 network 192.168.1.0 0.0.0.255 network 1.1.1.1 0.0.0.0 #
The boldfaced items in the command output show the configurations that have taken effect. Check that the OSPF VPN is correctly configured by checking the configurations of the OSPF process ID, tag value, and default route delivery. Step 5 Run the display ospf error command on the commissioning device to view OSPF errors. display ospf error OSPF Process 1 with Router ID 1.1.1.1 OSPF error statistics General packet errors: 0 : IP: received my own packet 0 : Bad version 0 : Bad area id 0 : Bad virtual link 0 : Bad authentication key 0 : Packet size > ip length 0 : Interface down

Troubleshooting If the OSPF neighbor relationship is Down after OSPF is configured, complete the following: 1.
Check logs to find the cause of the Down OSPF neighbor relationship. Run the display logbuffer command to view the following log information: NBR_DOWN_REASON(l): Neighbor state leaves full or changed to Down. (ProcessId= [USHORT], NeighborRouterId=[IPADDR], NeighborAreaId=[ULONG], NeighborInterface=[STRING],NeighborDownImmediate reason=[STRING], NeighborDownPrimeReason=[STRING], NeighborChangeTime=[STRING])

Check the NeighborDownImmediate reason field which records the cause of the Down OSPF neighbor relationship. Possible causes are as follows: l Neighbor Down Due to Inactivity It indicates that the local end does not receive any Hello packet from its neighbor within the deadtime, and hence the OSPF neighbor relationship becomes Down. In this case, go to Step 2. l Neighbor Down Due to Kill Neighbor It indicates that the interface or BFD session is in the Down state, or the reset ospf process command is run and hence the OSPF neighbor relationship becomes Down. In this case, check the NeighborDownPrimeReason field to find the specific cause of the fault. – If the NeighborDownPrimeReason field displays Physical Interface State Change, the interface status has changed. In this case, run the display interface [ interface-type [ interface-number ] ] command to check the interface status, and then rectify the interface fault. – If the NeighborDownPrimeReason field displays OSPF Process Reset, the reset ospf process command has been executed. Whether or not this command has been run can be ensured by checking the operation records or log information. – If the NeighborDownPrimeReason field displays BFD Session Down, the BFD session status has become Down. In this case, rectify the BFD fault. l Neighbor Down Due to 1-Wayhello Received or Neighbor Down Due to SequenceNum Mismatch It indicates that the OSPF status on the remote end becomes Down before the remote end sends a 1-Way Hello packet to the local end, causing the OSPF status on the local end to become Down as well. In this case, rectify the fault on the remote end. l In other cases, go to Step 9. 2.
Check that the link between the two ends works normally. Check that the link between the two ends is working normally, including the transmission devices. If the link works properly, go to Step 3.
3.
Check that the CPU usage is within the normal range. Check whether or not the CPU usage on the MPU or LPU of the faulty device is too high. If the CPU usage is too high, OSPF fails to receive and send protocol packets, causing the neighbor relationship to flap. In this case, rectify the high CPU usage fault. If the CPU usage is within the normal range, go to Step 4.
4.
Check that the interface status is Up. Run the display interface [ interface-type [ interface-number ] ] command to check the physical status of the interface. If the physical status of the interface is Down, rectify the interface fault. If the physical status of the interface is Up, run the display ospf interface command to check that the OSPF status of the interface is Up. display ospf interface OSPF Process 1 with Router ID 1.1.1.1 Interfaces Area: 0.0.0.0 IP Address

l If the OSPF status of the interface is Down, run the display ospf cumulative command to check whether or not the number of interfaces enabled with OSPF in the OSPF process exceeds the limit. If so, reduce the number of interfaces enabled with OSPF. display ospf cumulative OSPF Process 1 with Router ID 1.1.1.1 Cumulations IO Statistics Type Input Output Hello 28310 134625 DB Description 32 25 Link-State Req 17 9 Link-State Update 1051 657 Link-State Ack 606 982 ASE: (Disabled) LSAs originated by this router Router: 1 Network: 11 Sum-Net: 0 Sum-Asbr: 0 External: 0 NSSA: 0 Opq-Link: 0 Opq-Area: 20 Opq-As: 0 LSAs Originated: 32 LSAs Received: 1448 Routing Table: Intra Area: 11 Inter Area: 0 ASE: 0 Up Interface Cumulate: 6 Neighbor Cumulate: ======================================================= Neighbor cumulative data.

l If the OSPF status of the interface is normal (for example, DR, BDR, DR Other, or P2P), go to Step 5. 5.
Check that the IP addresses of the two ends are on the same network segment. l If the IP addresses of the two ends are on different network segments, modify the IP address of one end. l If the IP addresses of the two ends are on the same network segment, go to Step 6.
6.
Check that MTUs of the interfaces on both ends are consistent. If ospf mtu-enable is enabled on the interfaces, the interface MTUs must be consistent. Otherwise, OSPF neighbors cannot negotiate with each other successfully. l If MTUs of the interfaces on both ends are inconsistent, run the mtu mtu command in the interface view to change MTUs of the interfaces to be consistent on both ends. l If the MTUs of the interfaces on both ends are consistent, go to Step 7.
7.
Check that there is at least one interface whose priority is not 0. On the broadcast and NBMA networks, there should be at least one interface whose priority is not 0, which ensures that a DR is elected correctly. Otherwise, the state of the OSPF neighbor relationship can only reach 2-Way.

The preceding command output shows that the commissioning device has a reachable IS-IS route to the network connected to CX- B. ----End
Troubleshooting If the IS-IS neighbor relationship cannot be established after IS-IS is configured, complete the following: 1.
Check that IS-IS can receive and send Hello packets properly. Run the display isis statistics packet [ interface interface-type interface-number ] command to check that IS-IS can normally receive and send Hello packets. NOTE
The default interval at which IS-IS sends Hello packets is 10s. Therefore, run this command every 10s to check whether or not the packet statistics increase. On a broadcast interface, IS-IS Hello packets have IS-IS levels, and therefore you can view Hello packet statistics based on the levels of established neighbor relationships. On a P2P interface, IS-IS Hello packets have no IS-IS levels and are recorded as L2 IIH packets.
l If the number of received Hello packets does not increase for a certain period, check whether or not packet loss has occurred at the lower layer or at the link between the two ends. l If the number of received Hello packets increases gradually, perform the following operations based on interface types: – If the interfaces on both ends are trunk interfaces, check that the numbers of the trunk member interfaces in the Up state are the same on both ends. – If the interfaces on both ends are not trunk interfaces, go to Step 2. 2.
Check that the interface status is Up. Run the display ip interface [ interface-type interface-number ] command to check the status of a specified interface. l If the interface status is not Up, rectify the interface fault. For detailed troubleshooting procedures, see "Interface & Physical Connection Troubleshooting" and "Layer 2 Network Troubleshooting." l If the interface status is Up, go to Step 3.
3.
Check the status of IS-IS interfaces. Run the display isis interface command to check the status of the interfaces enabled with IS-IS. l If the interface status is Mtu:Dn/Lnk:Up/IP:Up, run the display currentconfiguration interface interface-type [ interface-number ] command to check the MTUs of the interfaces. Run the display current-configuration configuration isis

command to check the LSP length configured in the IS-IS process. On a P2P interface, the LSP length should not be greater than the MTU. On a broadcast interface, the value obtained by subtracting the LSP length from the MTU should be greater than or equal to 3. If these conditions are not met, change the MTU of the interface or the LSP length. l If the interface status is Down, run the display current-configuration configuration isis command to check the configuration of the IS-IS process. Check that the NET is configured in the IS-IS process. If not, configure the NET in the IS-IS process. l If the interface status is Mtu:Up/Lnk:Dn/IP:Dn, check that IS-IS interfaces are configured with IP addresses. l If the interface status is Up, go to Step 4. 4.
Check that the IP addresses of the two ends are on the same network segment. l If the IP addresses of the two ends are on different network segments, modify the IP address of one end. l If the IP addresses of the two ends are on the same network segment, go to Step 5.
5.
Check that both ends are configured with different system IDs. Run the display current-configuration configuration isis command to check whether or not the system IDs of the two ends are the same. l If the system IDs of the two ends are the same, set different system IDs for each end. l If the system IDs of the two ends are different, go to Step 6.
6.
Check that the IS-IS levels of the two ends are consistent. Run the display current-configuration configuration isis | include is-level command to check the levels of the IS-IS processes on both ends. Then, run the display currentconfiguration interface interface-type interface-number | include isis circuit-level command to check whether or not the IS-IS levels of the interfaces at both ends are consistent. The IS-IS neighbor relationship can only be established when the IS-IS levels of the two interfaces are consistent. l If the IS-IS levels of the interfaces at both ends are inconsistent, run the is-level command in the IS-IS view to change the IS-IS level of one end, or run the isis circuitlevel command in the interface view to change the IS-IS level of the interface. l If the IS-IS levels of the interfaces at both ends are consistent, go to Step 7.
7.
Check that the area addresses of the two ends are the same. When the area addresses of the two ends are different, the alarm isisAreaMismatch is generated. NOTE
If the two ends establish a Level-1 neighbor relationship, ensure that they are both in the same area. An IS-IS process can be configured with a maximum of three area addresses. As long as one of the area addresses of the local IS-IS process is the same as one of the area addresses of the remote IS-IS process, the Level-1 neighbor relationship can be established. When an IS-IS Level-2 neighbor relationship is established between two ends, you do not need to determine whether or not the area addresses of the two ends are the same.
l If the area addresses of the two ends are different, run the network-entity command in the IS-IS view to set the same area address for both ends. l If the area addresses of the two ends are the same, go to Step 8. 8. Issue 04 (2014-04-01)

If the authentication modes configured on the two ends are different, the alarm isisAuthenticationTypeFailure or isisAuthenticationFailure is generated. Run the display current-configuration interface interface-type interface-number | include isis authentication-mode command to check IS-IS authentication configurations on the interfaces of the two ends. l If the authentication modes configured on both are different, run the isis authenticationmode command in the IS-IS interface view on both ends to set the same authentication mode. l If the authentication password configured on both are different, run the isis authentication-mode command in the IS-IS interface view on both ends to set the same authentication password. l If the authentication modes configured on both ends are the same, go to Step 9. 9.

Troubleshooting If the BGP peer relationship cannot be established on a BGP-deployed network, complete the following: 1.
Run the ping command to check that BGP peers can ping each other successfully. l If they can ping each other successfully, it indicates that there are available routes between the BGP peers and that link transmission is normal. Proceed to Step 2. NOTE
Run the ping -a source-ip-address -s packetsize host command to detect the connectivity of each end. Because the source address is specified in this command, you can check whether or not routes between the two ends are accessible. By specifying the size of a Ping packet, you can also check whether or not long Ping packets can be normally transmitted over the link.
l If the ping fails, follow the procedure described in "The Ping Operation Fails" in the HUAWEI CX600 Metro Services Platform Troubleshooting to find whether or not the routing tables on each end have available routes to each other. 2. Issue 04 (2014-04-01)

Description
peer connect-interface interfacetype interface-number
If two ends use loopback interfaces to establish the BGP peer relationship, you need to run the peer connect-interface command to specify the associated loopback interface as the source interface that sends BGP packets.
peer valid-ttl-hops hops
If the peer valid-ttl-hops hops command is configured, check that the hops value is correct. The valid TTL range of the detected packet is [255 - hops + 1, 255]. hops specifies the hop count between BGP peers, and the hop count between two directly connected devices is 1. NOTE The peer valid-ttl-hops command must be configured on both ends before setting up the BGP session.
Issue 04 (2014-04-01)
peer route-limit limit
If the peer route-limit limit limit command is configured, check whether or not the number of routes sent by the peer exceeds the limit that is specified by limit. If it is exceeded, you need to reduce the number of routes sent from the peer, and run the reset bgp ip-address command to reset the BGP peer relationship and trigger the reestablishment of the BGP peer relationship.
peer ignore
If the peer ignore command is configured on the peer, it indicates that the peer is not required to establish the BGP peer relationship with the local end temporarily. To establish the BGP peer relationship between the remote peer and local peer, run the undo peer ignore command on the peer.

Troubleshooting If the BGP peer relationship cannot be established on a BGP-deployed network, complete the following: 1.
Run the ping command to check that BGP peers can ping each other successfully. l If they can ping each other successfully, it indicates that there are available routes between the BGP peers and that link transmission is normal. Proceed to Step 2. NOTE
Run the ping -a source-ip-address -s packetsize host command to detect the connectivity of each end. Because the source address is specified in this command, you can check whether or not routes between the two ends are accessible. By specifying the size of a Ping packet, you can also check whether or not long Ping packets can be normally transmitted over the link.
l If the ping fails, follow the procedure described in "The Ping Operation Fails" in the HUAWEI CX600 Metro Services Platform Troubleshooting to find whether or not the routing tables of each end have available routes to each other. Issue 04 (2014-04-01)

Check that no ACL is configured to filter packets whose destination port is TCP port 179. Run the display acl all command on both ends to check whether or not an ACL is configured to filter packets whose destination port is TCP port 179. display acl all Total nonempty ACL number is 1 Advanced ACL 3001, 2 rules Acl's step is 5 rule 5 deny tcp source-port eq bgp rule 10 deny tcp destination-port eq bgp
l If an ACL is configured to filter packets whose destination port is TCP port 179, delete the ACL configuration. l If no ACL is configured to filter packets whose destination port is TCP port 179, go to Step 3. 3.
Check that the peer router ID does not conflict with the local router ID. Check information about BGP peers to ensure that their router IDs do not conflict. For example, if the IPv4 unicast peer relationship fails to be established, you can run the display bgp peer command to check whether or not the peer router ID conflicts with the local router ID. Use the following command output as an example: display BGP local router Local AS number Total number of Peer PrefRcv 8.9.0.8 10000 9.10.0.10 9999

Description
peer connect-interface interfacetype interface-number
If two ends use loopback interfaces to establish the BGP peer relationship, you need to run the peer connect-interface command to specify the associated loopback interface as the source interface that sends BGP packets.
peer ebgp-max-hop hop-count
If two directly connected devices use loopback interfaces to establish the EBGP peer relationship or two indirectly connected devices establish the EBGP peer relationship, you need to run the peer ebgp-max-hop command to specify the maximum hop count between them. l If two directly connected devices use loopback interfaces to establish the EBGP peer relationship, the hop count can be any number greater than 1. l If two indirectly connected devices establish the EBGP peer relationship, you need to specify the actual hop count.
peer valid-ttl-hops hops
If the peer valid-ttl-hops hops command is configured, check that the hops value is correct. The valid TTL range of the detected packet is [255 - hops + 1, 255]. hops specifies the hop count between BGP peers, and the hop count between two directly connected devices is 1. NOTE The peer valid-ttl-hops command must be configured on both ends before setting up the BGP session.

peer route-limit limit
If the peer route-limit limit command is configured, check whether or not the number of routes sent by the peer exceeds the limit specified by limit. If it is exceeded, you need to reduce the number of routes sent from the peer, and run the reset bgp ip-address command to reset the BGP peer relationship and trigger the reestablishment of the BGP peer relationship.
peer ignore
If the peer ignore command is configured on the peer, it indicates that the peer is not required to establish the BGP peer relationship with the local end temporarily. To establish the BGP peer relationship between the remote peer and local peer, run the undo peer ignore command on the peer.
Address family capability
Check that the address family capabilities of on both ends match. For example, before establishing the BGP VPNv4 peer relationship, you need to configure the peer enable command in the BGP-VPNv4 address families of the two ends. If the peer enable command is only configured on one end, the BGP peer relationship of the other end is displayed as No neg.

Troubleshooting If the established TE tunnel is in the Down state on a TE-deployed network, complete the following: 1.
Check that the commit command has been executed to commit tunnel configurations. Run the display current-configuration command on the ingress that is configured with the TE tunnel. l If the commit command has not been executed, run it in the tunnel view. l If the commit command has been executed in the tunnel view, go to Step 2.
2.
Check that CSPF has been successfully calculating paths. Run the display mpls te cspf destination ip-address explicit-path path-name command on the TE tunnel ingress. If command output is displayed, CSPF has been successfully calculating paths; if no command output is displayed, CSPF failed to calculate a path. l If CSPF failed to calculate a path, check that routes to the destination of the TE tunnel exist. – If no route exists, follow the procedure described in "The Ping Operation Fails" in the HUAWEI CX600 Metro Services Platform Troubleshooting to rectify the route fault. – If reachable routes exist and they satisfy the requirements to establish a TE tunnel, rectify the fault by referring to the section "CSPF Calculation Fails." l If CSPF has been successfully calculating paths but the fault persists, go to Step 3.
3.
Check that RSVP is enabled on every device along the TE tunnel. The command output of display mpls te cspf destination ip-address explicit-path pathname in Step 2 contains a series of IP addresses. These IP addresses indicate the hops along the TE tunnel. On the interface mapped to each IP address, run the display currentconfiguration interface interface-name command to check if RSVP is enabled. l If an interface is not enabled with RSVP, enable RSVP on the interface. l If all interfaces are enabled with RSVP but the fault persists, go to Step 4.
4.
Check that devices along the TE tunnel have been successfully exchanging RSVP Path and Resv messages.

Check that the number of BGP peers and the number of configured VPN instances are correct. The boldfaced items in the command output show that the BGP peer relationship is in the Established state, indicating that a BGP peer relationship has been successfully established between PEs. Step 3 Run the display bgp vpnv4 routing-table command on the commissioning device to view BGP VPNv4 routing information. display bgp vpnv4 vpn-instance vpna routing-table peer 100.1.1.1 advertised-routes BGP Local router ID is 1.1.1.1 Status codes: * - valid, > - best, d - damped, h - history, i - internal, s - suppressed, S - Stale Origin : i - IGP, e - EGP, ? incomplete Total Number of Routes: 6 Network NextHop MED LocPrf PrefVal Path/ Ogn *>i 2.2.2.2/32 1.1.1.1 0 100 0 65420? *> 100.1.1.0/24 0.0.0.0 0 0 ? *>i 100.1.2.0/24 1.1.1.1 0 100 0 ? *>i 192.168.1.0 1.1.1.1 0 100 0 65420? display bgp vpnv4 vpn-instance vpna routing-table peer 100.1.1.1 receivedroutes BGP Local router ID is 1.1.1.1 Status codes: * - valid, > - best, d - damped, h - history, i - internal, s - suppressed, S - Stale Origin : i - IGP, e - EGP, ? - incomplete VPN-Instance vpna, router ID 1.1.1.1: Total Number of Routes: 6

Check that the sent and received BGP routes are correct. First check whether the routes sent by the PE are correct, meaning whether some necessary routes are not sent but some unnecessary routes are sent. Then do the same for the routes received from the peer PE. Step 4 Run the display ip routing-table vpn-instance command on the commissioning device to view the routing table of the VPN instance. display ip routing-table vpn-instance vpna Route Flags: R - relay, D - download to fib -----------------------------------------------------------------------------Routing Tables: vpna Destinations : 3 Routes : 3 Destination/Mask Proto Pre Cost Flags NextHop Interface 100.1.1.0/24 Direct 0 0 D 10.1.1.2 GigabitEthernet1/0/0 100.1.1.2/32 Direct 0 0 D 127.0.0.1 InLoopBack0 100.1.1.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0 100.1.2.0/24 BGP 255 0 RD 2.2.2.2 GigabitEthernet1/0/0 255.255.255.255/32 Direct 0 0 D 127.0.0.1 InLoopBack0
The command output shows whether the received BGP routes are injected into the routing table of the VPN instance. If BGP routes are received but are not injected into the routing table of the VPN instance, the probable cause is that the public network tunnel is not established, or the routes are filtered by a routing policy. The boldfaced items in the command output show the route to the interface on the remote CE. Step 5 Run the ping command on CE1 to test the connectivity of the link between CE1 and CE2. ping -vpn-instance vpna 100.1.2.2 PING 100.1.2.2: 56 data bytes, press CTRL_C to break Reply from 100.1.2.2: bytes=56 Sequence=1 ttl=255 time=56 ms Reply from 100.1.2.2: bytes=56 Sequence=2 ttl=255 time=4 ms Reply from 100.1.2.2: bytes=56 Sequence=3 ttl=255 time=4 ms Reply from 100.1.2.2: bytes=56 Sequence=4 ttl=255 time=52 ms Reply from 100.1.2.2: bytes=56 Sequence=5 ttl=255 time=3 ms --- 100.1.2.2 ping statistics --5 packet(s) transmitted 5 packet(s) received 0.00% packet loss round-trip min/avg/max = 3/23/56 ms
The preceding command output shows that two CEs in the same VPN can communicate with each other. ----End
Troubleshooting If BGP traffic in the VPN is interrupted, complete the following: 1.
Check that next hops of routes are reachable. Run the display bgp vpnv4 vpn-instance vpn-instance-name routing-table ipv4address [ mask | mask-length ] command on the PE that sends routes (the local PE) to check that the target route exists. ipv4-address specifies the prefix of the target route.

l If the target route does not exist, check whether the route of a CE is advertised to the local PE. l If the target route exists, check that it is active. The following is an example: Assume that the target route is a route to 1.1.1.1/32. The following command output shows that this route is active and selected. The original next hop and iterated next hop of this route are 3.3.3.3 and 20.1.1.2 respectively. display bgp vpnv4 vpn-instance vpna routing-table 1.1.1.1 BGP local router ID : 20.1.1.2 Local AS number : 100 VPN-Instance vpna, router ID 20.1.1.2: Paths: 1 available, 1 best, 1 select BGP routing table entry information of 1.1.1.1/32: Imported route.

l If the target route is inactive, check whether there is a route to the original next hop in the IP routing table. If there is no route to the original next hop, the BGP route is not advertised, because its next hop is unreachable. Then, find out why there is no route to the original next hop (this fault is generally associated with IGP or static routes). l If the target route is active but not selected, check whether there is a route with a higher protocol preference in the IP routing table. If there is a route with a higher protocol preference, import it into BGP or adjust its protocol preference. If there is no route with a higher protocol preference, contact Huawei technical support personnel. NOTE
In the BGP routing table, multiple routes may have the same prefix. One of these routes can be selected at most, and only the selected route is added to the IP routing table and sent to the peer. When an optimal route needs to be selected from among BGP routes and other protocol routes, the route with the highest protocol preference is selected.
l If the target route is active but not selected, contact Huawei technical support personnel. NOTE
If there are active BGP routes, one of them is preferred.
l If the target route is active and selected but there is no information indicating that this route is sent to the remote PE, perform Step 2 to check the outbound policy applied to the local PE. Run the display bgp vpnv4 all routing-table network { mask | mask-length } command on the remote PE to check that it has received the target route. – If the remote PE has received the target route, perform Step 1 again to check whether the next hop of the route is reachable and whether this route is selected. – If the remote PE has not received the target route, perform Step 2 to check the inbound policy applied to the remote PE. 2.
Check that the routing policies are configured correctly. Run the display current-configuration configuration bgp command on the local PE and remote PE to check that inbound and outbound policies are configured.

Check that MPLS is enabled on the local PE. Then, run the display bgp vpnv4 all routingtable ipv4-address [ mask | mask-length ] command to check whether the target route has been assigned a VPN label.

l If labels are insufficient, run the apply-label per-instance command in the VPN instance view to configure the device to assign a label to each instance to save labels. You can also configure route summarization to reduce the number of routes. l If labels are sufficient, go to Step 6. 6.
Check that the number of routes does not exceed the limit. Run the display current-configuration configuration bgp | include peer destinationaddress command and the display current-configuration configuration bgp | include peer group-name command (if the peer is added to a peer group) on the remote PE to check whether the limit on the number of routes to be received is configured on the remote PE. For example, if the limit is set to 5, subsequent routes are dropped and a log is recorded after the remote PE receives five routes from the local PE at 1.1.1.1. display current-configuration configuration bgp | include peer 1.1.1.1 peer 1.1.1.1 as-number 100 peer 1.1.1.1 route-limit 5 alert-only peer 1.1.1.1 enable

In this case, you need to run the display current-configuration configuration bgp | include peer group-name command to check the configurations of this peer group. display current-configuration configuration bgp | include peer IBGP peer IBGP route-limit 5 alert-only peer IBGP enable
If the log BGP/3/ROUTPRIX_EXCEED is generated when traffic is interrupted, the target route is dropped because the route limit has been exceeded, and the limit needs to be increased. NOTE
Changing the limit on the number of routes to be received from a peer interrupts the BGP peer relationship. Therefore, it is recommended to reduce the number of sent routes by configuring route summarization on the local device.

Troubleshooting If the BFD session cannot become Up, complete the following: 1.
Run the display current-configuration configuration bfd-session command to check whether or not BFD session configurations have been committed. l If the commit field is displayed, BFD session configurations have been committed. Then go to Step 2. l If the commit field is not displayed, BFD session configurations have not been committed. In this case, run the commit command in the BFD session view, and then run the display bfd session all command to check that the BFD session is Up. – If the State field is displayed as Up, the BFD session has been created and no action is required. – If the State field is not Up, go to Step 2.
2.
Run the display bfd statistics session all slot slot-id command repeatedly to check statistics about BFD packets. l If the Received Packets value does not increase, go to Step 3. l If the Send Packets value does not increase, go to Step 4. l If both the Received Packets and Send Packets values increase properly, go to Step 7. l If none of the Received Packets, Send Packets, Received Bad Packets, and Send Bad Packets values increases, go to Step 5. l If the Down Count value increases, the BFD session flaps. In this case, go to Step 5.
3.
Run the display bfd statistics session all slot slot-id command repeatedly to check that the Received Bad Packets value increases properly. l If the Received Bad Packets value increases, the local end receives but discards the BFD packets sent from the remote end. In this case, go to Step 7. l If the Received Bad Packets value does not increase, the local end does not receive BFD packets. In this case, go to Step 5.
4.
Run the display bfd statistics session all slot slot-id command repeatedly to check that the Send Bad Packets value increases properly. l If the Send Bad Packets value increases, the BFD packets are sent but discarded. In this case, go to Step 7.

l If the Send Bad Packets value does not increase, the local end does not send BFD packets to the remote end. In this case, go to Step 5. 5.
Run the display bfd statistics session all slot slot-id command repeatedly. If the BFD session still does not go Up, run the ping command on one end to ping the other end of the BFD session. l If the ping fails, follow the procedure described in "The Ping Operation Fails" in the HUAWEI CX600 Metro Services Platform Troubleshooting to rectify the packet forwarding fault. l If the ping succeeds, go to Step 6.
6.
Run the display current-configuration configuration bfd-session command to check the min-tx-interval and min-rx-interval values and determine whether or not the detection time value is larger than the delay value. l If the detection time value is smaller than the delay value, run the detect-multiplier, min-rx-interval, or min-tx-interval command to change the detection time value of the BFD session to be larger than the delay value. l If the detection time value of the BFD session is larger than the delay value, go to Step 7.

Troubleshooting If OSPF FRR forwarding fails, perform the following steps: 1.
Run the display ospf peer command to check whether the OSPF neighbor relationship has been established. display ospf peer OSPF Process 1 with Router ID 1.1.1.1 Neighbors Area 0.0.0.0 interface 1.3.1.1(GigabitEthernet1/0/2)'s neighbors Router ID: 4.4.4.4 Address: 1.3.1.3 GR State: Normal State: Full Mode:Nbr is Slave Priority: 1 DR: 1.3.1.3 BDR: None MTU: 0 Dead timer due in 35 sec Retrans timer interval: 5 Neighbor is up for 00:00:05 Authentication Sequence: [ 0 ]
In the preceding command output, check whether the number of neighbors is correct, whether the State field displays Full, and whether the neighbor is Up for a long time. If the State field displays Full, LSDB synchronization is complete, and the OSPF neighbor relationship is Full. If the neighbor is Up for a short period of time, the OSPF neighbor relationship was recently interrupted. l If the OSPF neighbor relationship has not been established, see the chapter OSPF in HUAWEI CX600 Metro Services Platform Troubleshooting. l If the OSPF neighbor relationship has been established, go to Step 2. 2.
Run the display current-configuration configuration ospf command to check whether OSPF IP FRR has been enabled. display current-configuration configuration ospf # ospf 1 router-id 1.1.1.1 frr frr-policy route route-policy abc loop-free-alternate area 0.0.0.1 network 1.2.1.0 0.0.0.255 network 1.3.1.0 0.0.0.255
If OSPF IP FRR has been enabled, go to Step 3. If OSPF IP FRR has not been enabled, see the chapter "Configuring OSPF IP FRR" in HUAWEI CX600 Metro Services Platform Configuration Guide - IP Routing. 3. Issue 04 (2014-04-01)

l
The link layer has been commissioned. For more information, see 5 Commissioning the Link Layer.
Context On the network shown in Figure 6-17, LSRA, LSRB, and LSRC are equipped with dual main control boards. Three LSRs learn routes from one another using the IS-IS protocol and then use the RSVP protocol to establish a TE tunnel from LSRA to LSRC. RSVP GR is required to ensure that MPLS forwarding is not interrupted when ae master/slave switchover of main control boards occurs on LSRA, LSRB, or LSRC.

6.18 Commissioning CR-LSP Hot Standby This section describes how to commission CR-LSP Hot Standby.
Prerequisites l
The hardware has been checked. For more information, see 4 Checking the Hardware.
l
The link layer has been commissioned. For more information, see 5 Commissioning the Link Layer.
Context Figure 6-19 illustrates an MPLS VPN. A TE tunnel originates from the ingress PE1 and terminates at the egress PE2. CR-LSP hot backup and best-effort LSPs need to be configured. The following LSPs need to be established: l
Primary CR-LSP along the path PE1 --> P1 --> PE2
l
Backup CR-LSP along the path PE1 --> P2 --> PE2
If the primary CR-LSP fails, traffic switches to the backup CR-LSP. After the primary CR-LSP recovers from the fault, traffic switches back to the primary CR-LSP in 15 seconds. If both the primary and backup CR-LSPs fail, traffic switches to the best-effort LSP. If both the primary and backup CR-LSPs fail, traffic switches to the best-effort path. Explicit paths can be configured for the primary and backup CR-LSPs. A best-effort path can be generated automatically. In this example, the best-effort path is PE1 -> P2 -> P1 -> PE2. The calculated best-effort path varies according to the faulty node.

Procedure Step 1 Assign an IP address to each interface. Assigne an IP address and mask to each interface, create loopback interfaces on LSRs, and configure the IP addresses of loopback interfaces as MPLS LSR IDs, according to Figure 6-19. Step 2 Configure an IGP. Configure OSPF or IS-IS on each LSR to enable communication between LSRs. In this example, IS-IS is configured. Step 3 Configure basic MPLS functions. On each LSR, configure an LSR ID and enable MPLS in the system view and in the interface view. Step 4 Configure basic MPLS TE functions. Enable MPLS-TE and MPLS RSVP-TE in the MPLS view and the interface view on each LSR. Set the maximum reservable bandwidth of links to 100 Mbit/s and the bandwidth of BC0 to 100 Mbit/s. Step 5 Configure IS-IS TE and CSPF. Issue 04 (2014-04-01)

In this example, both PE2 and PE3 advertise the route 10.3.1.1/24 with the same BGP attribute to PE1. The router ID of PE2 is smaller than that of PE3 so that PE1 preferentially selects the route advertised by PE2, that is, Link_A. If the router ID of PE2 is greater than that of PE3 in a real-world situation, PE1 preferentially selects the route advertised by PE2, that is, Link_B. In this case, VPN FRR fails if the preceding configurations are followed. To prevent the problem from occurring, you can modify VPNv4 route attributes in the BGP-VPNv4 address family view, ensuring that PE1 preferentially selecting Link_A. There are many methods to modify VPNv4 route attributes. The following part shows the most common two methods: l In the BGP-VPNv4 address family view of PE1, set a higher PrefVal for the routes learnt from PE2. The relevant configuration is as follows: route-policy policy1 permit node 10 apply preferred-value 100 # bgp 100 # ipv4-family vpnv4 peer 2.2.2.2 route-policy policy1 import
l In the BGP-VPNv4 address family view of PE2, set a higher Local_Pref for the advertised routes. The relevant configuration is as follows: route-policy policy2 permit node 10 apply local-preference 200 # bgp 100 # ipv4-family vpnv4 peer 1.1.1.1 route-policy policy2 export

7.1 Example for Commissioning an IP Bearer Network This section provides an example about how to commission an IP bearer network.
Prerequisites The CX600s are installed, cabled, and loaded with configuration scripts.
Networking Figure 7-1 shows an IP core bearer network that provides multiple services such as 3G, Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), and Internet services. This network consists of two layers, the core layer and the access layer. l
Core layer – This layer has two planes with each plane having five nodes that are fully meshed and located in five cities. The nodes on different planes are connected to each other through 10 Gbit/s Ethernet links, and backup paths are provided. – Intermediate System-to-Intermediate System (IS-IS) is used as an Interior Gateway Protocol (IGP) at the core layer, and Traffic Engineering (TE) tunnels are established between Ps on the same plane.
l
Access layer – Each NGW is dual-homed to two switches. Each switch is separately connected to a PE. The Virtual Router Redundancy Protocol (VRRP) runs between the PEs and switches, ensuring high availability of the link between the two switches. – EBGP peer relationships are established between the PEs and RRs at the core layer. – Remote LDP sessions are established between the PEs at different sites. – The PEs at the same site are connected to each other, switches, and core nodes by GE links. On each PE, the interface connected to a switch is called the user-side interface, and the interface connected to the backbone network is called the network-side interface. The user-side interface contains multiple sub-interfaces with each sub-interface being bound to a VPN instance and serving as the gateway for the corresponding CE. BFD runs on main interfaces.

The 10G XFP multi-mode optical transceiver supports two types of multi-mode optical fibers with different cores. Table A-26 lists the relationship between the core, the modal/bandwidth, and the transmission distance. During configuration, the length of optical fibers is restricted by the transmission distance. In addition, the optical fiber with the 50 um core and 2000 MHz*km modal/bandwidth is a special type, which is not delivered by Huawei. If this type of optical fiber is required, you need to purchase it additionally. Table A-26 Transmission distance of the 10G XFP optical modules Core Fiber (μm)
