NMS
It indicates network management software running on a workstation. The administrator sends requests to managed NEs on the NMS for monitoring and configuring NEs.
Agent
It indicates an agent process running on a managed NE. After the managed NE receives a request sent by the NMS, the agent responds to the request. An agent is mainly used for collecting NE status information, performing operations on NEs remotely on the NMS, and sending an alarm to the NMS.
MIB
It indicates a virtual database considered as an NE status set maintained on NEs. The agent collects NE status information by searching MIB.

1 Overview
SNMP supports five types of protocol data units (PDUs), as follows: Table 1-3 PDU type PDU
Function
GetRequest-PDU
It is used for accessing an agent and obtaining variable values from the table.
GetNextRequest-PDU
It can obtain the next logical ID descriptor from MIB. Its functions are the same as those of GetRequest-PDU except this function.
GetResponse-PDU
It is used for responding to GetResponse, GetNextResponse, and SetRequest PDUs. It contains the ID descriptors relevant to the preceding PDUs and provides ID descriptors of response status information, such as error codes, error status, and supplementary information list.
SetRequest-PDU
It describes the action acting on an element. Typically, it is used for modifying the values in the variable list.
Trap-PDU
It allows the network management module to report an event occurred on an NE or status change of an NE.
1.2.3 MIB Description This chapter provides the basic concepts of MIB. The MIB is a key part of the SNMP network management framework. The MIB is the object set managed by SNMP, including all the variables to be managed. All the SNMP operations such as Get and Set, aim at the managed objects in the MIB. The MIB defines the managed objects that are used by the function interfaces of the SNMP Northbound Interface. The definitions decide what operations the NMS can do and what network management information the NMS can obtain. The international organization assigns MIB node 2011 to Huawei Technologies Co., Ltd (HUAWEI). HUAWEI assigns MIB node 2011.2.15 to the NMS. The NMS assigns MIB node 1 as hwNmAgent. Therefore, the complete MIB node information is: iso(1).org(3).dod(6).internet(1).private(4).enterprises(1).huawei(2011).products (2).hwNetManagement(15).hwNmAgent(1) IHW-IMAPV1NORTHBOUND-TRAP-MIB defines the root node information of the SNMP Northbound Interface. The SNMP Northbound Interface further assigns the MIB node information based on the root node.

1.3.1 Overview The security mechanism of the U2000 SNMP NBI is also the security mechanism of SNMP. Any access to the SNMP alarm NBI must be authenticated. Figure 1-4 shows that SNMP v1 and v2c use the community-based security mechanism, while SNMP v3 uses the user-based security mechanism. Figure 1-4 Security mechanism NMS
v1/v2c use community name based security mechanism
v3 uses user based security mechanism
SNMP alarm northbound interface
1.3.2 Security Mechanism of SNMP v1 and v2c This section describes the security mechanism of SNMP versions v1 and v2c. The security mechanism of SNMP v1 and v2c is community-based. The packet is sent in plain text that is easy to be intercepted or modified. Compared with SNMP v3, the security is weaker. Before the Get, Get Next or Set operation, NMS must know the community strings configured in the agent. For set operations, NMS must know the write community configured in the agent. For get operations, NMS must know the read community configured in the agent. In the Trap and Inform packets, the community name is the first read community configured in the agent.
1.3.3 Security Mechanism of SNMP v3 This section describes the security mechanism of SNMPv3 version. SNMPv3 adopts the user-based security mechanism. The authentication and encryption mechanisms are used during the interaction with SNMP. To do read and write operations to agent, user must know: l
SNMP v3 user name in the Agent.
l
Security level.
l
The authentication and/or privacy passwords information.
The trap packets can be correctly resolved and handled only when the receiving end knows authentication parameters configured at agent correctly. Issue 01 (2010-05-18)

About This Chapter The SNMP Northbound Interface provides different function interfaces to the different NMSs. 2.1 Reporting Fault Alarms in Real-Time The SNMP Northbound Interface reports the real-time fault alarms to the NMS, so that the NMS can get the exact information of NE real-time alarms. 2.2 Querying Current Alarms Through the SNMP NBI of the U2000, the upper layer NMS can query the current alarms (unterminated alarms) of the U2000. 2.3 Alarm handshaking and Caching Real time alarms are sent through Inform to the third party NMS. When the NMS is down due to some failure at its side, real-time alarms are cached. When the failure is rectified, all the cached alarms are sent to the NMS in the order in which they were received from the EMS. 2.4 Traps This chapter introduces the trap configuration information of the SNMP Northbound Interface.

The format for setting the value of MIB node is as follows: IP Address: Port: AlarmFilterLevel The IP address and the port number are the same as specified in the snmp_agent_svc.xml file and the alarm filter level is the condition for filtering the alarms.
CAUTION Enter the IP address and port number of the upper-layer OSS. NOTE
l
On the Windows OS, the configuration file snmp_agent_svc.xml in the %IMAPROOT%\server\etc \conf.
l
On the Solaris or SUSE Linux OS, the configuration file snmp_agent_svc.xml in the $IMAPROOT/ server/etc/conf.
The alarm filter level is represented in four bits in binary notation. The alarm severity levels that can be filtered are critical, major, minor, and warning. Table 2-2 lists the meanings of each bit of the alarm filter level. If a bit is set to 0, it indicates that the alarms of the corresponding severity level are reported. If a bit is set to 1, it indicates that the alarms of the corresponding severity level are filtered out. Table 2-2 Alarm filter level Most Significant Bit (MSB) Critical Alarm
Least Significant Bit (LSB) Major Alarm
Minor Alarm
Warning Alarm
The alarm category filter condition is represented in three bits in binary notation. The alarm severity levels that can be filtered are event, fault, and recovery. Table 2-3 lists the meanings of each bit of the alarm category filter condition. If a bit is set to 0, it indicates that the alarms of the corresponding alarm category are reported. If a bit is set to 1, it indicates that the alarms of the corresponding alarm category are filtered out. Table 2-3 Alarm category filter Condition Most Significant Bit (MSB) Event

Example The IP address of the upper-layer OSS is set to 10.70.73.159 and the serial number of the port for receiving alarms is set to 161. To report only the critical and major alarms and filter out the minor and warning alarms, you need to set the MIB node to 10.70.73.159:161:0011.
2.2.2 Synchronizing Alarms Fault alarm synchronization is a process in which the alarms are queried by the third party NMS so that the alarms are consistent between upper NMS and EMS.
Context NMS can specify the time interval for alarm synchronization. This function adopts SNMP Trap or Inform mode depending upon the configuration done in the snmp_agent_svc.xml file. NOTE
l
On the Windows OS, the configuration file snmp_agent_svc.xml in the %IMAPROOT%\server\etc \conf.
l
On the Solaris or SUSE Linux OS, the configuration file snmp_agent_svc.xml in the $IMAPROOT/ server/etc/conf.

Procedure Step 1 Set the MIB node exposed. Set the hwNmNorthboundEventSynchronizationCommandStart node in the format as specified. IP address of the NMS: Port number of the NMS: Start Time: End Time The IP address and Port are same as configured in the snmp_agent_svc.xml file. Start Time and End Time parameters are in UTC time format and are optional. The syntax for start time and end time is: YYYYMMDDhhmmss. The variable description is as follows: l
YYYY: Four digit year. The range of values is 1970 onwards.
l
MM: Two digit month. The range of values is 01-12.
l
DD: Two digit date. The range of values is 01-31.

For Example, Valid query conditions: 10.18.38.63:20061006090520:20061006090520 - Start time and end time are specified. 10.18.38.63:161:20061006090520 - No end time is specified. The SNMP Northbound Interface sends a start synchronization notification to the NMS with the following OID: 1.3.6.1.4.1.2011.2.15.1.7.7.4 Alarm synchronization starts. Step 2 Receive active alarms present in the EMS Database. The NMS receives the active alarms present in the EMS Database between time period specified (if any). The OID of the synchronous data is: 1.3.6.1.4.1.2011.2.15 The OID carries the same VBs. The field formats are the same as those for a real-time alarm. The alarms can be synchronized for the NMSs configured in the snmp_agent_svc.xml file. Step 3 End alarm synchronization. The alarm synchronization ends after all active alarms are sent to the NMS or the NMS user sends the stop alarm synchronization request to the SNMP Northbound Interface.. Set hwNmNorthboundEventSynchronizationCommandStop node in the format as specified: IP Address: Port Number The IP Address and the port number is the address of the NMS for which alarm synchronization is to be stopped The SNMP alarm Northbound Interface sends a notification to the NMS which contains the result of synchronization. 1.
Alarm synchronization has been successfully ended.
2.
Alarm synchronization is stopped by the NMS command.
3.
Error has occurred during the alarm synchronization. NOTE
l
If End Time is not present, the current system time of the EMS is treated as the End Time.
l
If both are not present all the active alarms are queried.
l
If End Time is present Start Time is mandatory.

NOTE
The alarm trap notification is the same for real-time alarm reporting and as a response to querying active alarms.
How to configure AdditionalVB Additional VBs are not defined in agent. New type of additional VB can be added without changing the agent. Only snmp_agent_svc.xml needs to be changed. They do not have its own OID and use fixed OID assigned to additional information. They will use OID according to their order in the additional vbs. NOTE
l
On the Windows OS, the configuration file snmp_agent_svc.xml in the %IMAPROOT%\server\etc \conf.
l
On the Solaris or SUSE Linux OS, the configuration file snmp_agent_svc.xml in the $IMAPROOT/ server/etc/conf.
For example, the first VB in the additional VBs will use HwNmNorthboundAdditionalVB1 (1.3.6.1.4.1.2011.2.15.1.7.1.16.0) The second VB in the additional VBs will use HwNmNorthboundAdditionalVB2 (1.3.6.1.4.1.2011.2.15.1.7.1.17.0) The eighth VB in the additional VBs will use HwNmNorthboundAdditionalVB8 (1.3.6.1.4.1.2011.2.15.1.7.1.23.0). 2-16

The maximum number of count of additional VBs is eight. Only the first 8 additional VBs will be sent, and the other VBs are ignored. The field for additional VBs can be configured by the user, the format is as follows: AdditionalVBX=DEFINE_FIELD_NAME, Here X must begin from 1 and increase by 1 each time. To configure the values for each additional VB which maps to the array index of the Paras parameter, is sent in FM alarm structure. The datatype of the additional VBs is Octect string. If the value configured in the snmp_agent_svc.xml file does not match with the array index of the Paras parameter, null will be reported to the NMS.
2.4.3 Alarm Query Start Trap This section describes the alarm query start trap including the prerequisites and trap definition.
Description The U2000 notifies the NMS of the start of the query. After the NMS receives the active alarm query start trap, the query starts.

About This Chapter This chapter describes how to deploy and configure the U2000 SNMP NBI. It includes the following information: 3.1 Overview This topic describes the background information and the terms involved in the process of deploying and configuring the northbound interface. 3.2 Configuration Requirements U2000 SNMP NBI and the U2000 server run on the same PC or Sun workstation, any additional configuration is not required. But to enable the SNMP NBI, you must purchase the license for the corresponding functions. 3.3 Logging in to the Client of the NMS Maintenance Suite After you log in to the client of the NMS Maintenance Suite, you can maintain the U2000 by using the NMS Maintenance Suite, including deploying the U2000 and configuring the instance of the northbound interface. 3.4 Checking the SNMP NBI Status After check the license and ensure it is support SNMP functions, you need to check the current status of SNMP NBI, and deploy the SNMP NBI according the status. 3.5 Deploying the SNMP NBI for the First Time By default, the SNMP NBI is not installed during the installation of U2000 server. To enable the SNMP NBI, you need to add the SNMP NBI the SNMP NBI component first, then add the SNMP NBI instance. 3.6 Configuring the SNMP NBI In order to enable the SNMP NBI, even though you have installed SNMP NBI component, you need configure the SNMP parameters accord to NMS planning. Also, you can modify the parameters by configuring SNMP NBI again. As usual, the general parameters is mandatory. The advanced items is optional while the default value is recommended. Every advanced item is independence and you need not set the parameters in sequence. 3.7 SNMP Configuration Parameters

3 Deploying and Configuring SNMP
3.1 Overview This topic describes the background information and the terms involved in the process of deploying and configuring the northbound interface.
Attention Item l
Northbound interface is an optional component of the U2000. A license is required for using this function.
l
If you do not install the northbound interface component during the installation of the U2000, you need to add it manually.
l
The northbound interface is a System single-instance deployment package. Therefore, only one instance can be deployed.
CAUTION l
After the northbound interface component is installed or added, you need to add a corresponding instance and configure parameters. Then, the U2000 can start the NBI-related process.
l

Set reporting notification The upper layer NMS obtains alarm information through the SNMP agent in two ways: active reporting and active query. You can set the mode for sending alarms through the deployment tool and set parameters for different alarm obtaining modes.
WARNING l
Trap (passive reporting) : The SNMP agent reports alarms only after receiving a request from the upper layer NMS.
l
Inform (active reporting): The SNMP agent reports alarms once alarms are generated. In this mode, if the parameters configured for the upper layer NMS are incorrect, the SNMP agent tries connecting to the upper layer NMS for many times. This will occupy a large number of resources. As a result, the efficiency of the SNMP agent is reduced. Therefore, exercise caution when you set this parameter to Inform.

The U2000 administrator sets U2000 to support SNMPv1.
2.
The U2000 administrator configures community name, NMS IP address and port number, filter alarm category and alarm level.
3.
The NMS obtains IP address and port number (4700 by default) of the SNMP Northbound Interface from U2000 administrator.
Accessing U2000 by SNMPv2c For NMS to access U2000, ensure that: 1.
The U2000 administrator sets U2000 to support SNMPv2c.
2.
The U2000 administrator configures community name, NMS IP address and port number, filter alarm category and alarm level.
3.
The NMS obtains the IP address and port number (4700 by default) of the SNMP Northbound Interface from the U2000 administrator.
