IBM Network Advisor Deployment and Best Practices Guide
Introduction The purpose of this document is to present a set of guidelines that incorporate IBM best practices for deploying IBM Network Advisor (a.k.a. Brocade Network Advisor). This guide should act as a reference point in establishing consistent, standard deployments across IBM environments. The best practices noted in this guide present some the more advanced features of Brocade Fabric OS (FOS) for example, Fabric Watch, Bottleneck Detection, and Port Fencing. Additional best practices are provided for hardware selection, zoning, and performing scheduled health-related checks and tasks in the SAN. The guidance found in this document should provide you with an efficient, economic, and effective process by which to deploy and begin managing IBM Network Advisor.
NOTE: All deployments should be done using the Enterprise version of IBM Network Advisor.
When to use Network Advisor All SAN Fabric installations using Brocade technology should deploy IBM Network Advisor If you are currently managing your Brocade SAN with DCFM, you should upgrade to Network Advisor per the following:
All 16Gb installations (or prior to upgrading to 16Gb)
Prior to upgrading any Brocade FOS product to level 7.x or above
NOTE: DCFM is not qualified or supported for management of switches operating with FOS v7.0 and later firmware versions. You must first upgrade DCFM to Network Advisor 11.1 or later if you are planning to upgrade devices to FOS v7.0 or you risk losing management connectivity.

IBM Network Advisor Deployment and Best Practices Guide
Best Practices Recommendations The following recommendations are based on best practice recommendations from Brocade and IBM technical support groups.
Install and use Network Advisor to manage all switches. See Network Advisor Setup Switch configuration backup. See Backup and Restore Configuration Data Enable Bottleneck Credit Recovery Tools. See Bottleneck Credit Tools Configure Call Home and SNMP or email event notification. See Event notification Switches running FOS 7.2 or higher setup MAPS. See Monitoring and Alerting Policy Suite (MAPS) Switches running FOS 7.1 or lower setup Fabric Watch. See Fabric Watch Configure and enable Bottleneck Detection. See Bottleneck Detection Configure Network Advisor Dashboards. See Network Advisor Dashboards Implement and follow regular SAN health tasks. See Regular Tasks for SAN Health

IBM Network Advisor Deployment and Best Practices Guide
Regular Tasks for SAN Health NOTE: The below should be considered mandatory tasks to be performed in any Brocade SAN environment. Consistent execution of these tasks will help to ensure your fabrics are operating optimally, and that you have adequate backup data available for unexpected impacts to the SAN. Additionally, performing these tasks will provide you with information which can be extremely useful in recognizing trends and also targeting sources of problems in assisting with the troubleshooting process.
Daily Review of Event Logs The Master Log should be reviewed daily by the operations team as part of the health check process. Network Advisor’s Master Log lists all events and alerts that have occurred in the SAN and you should make it a habit of reviewing this log on a daily basis.
View specific logs by selecting an option from the Monitor menu’s Logs submenu. The following logs can be found here: Audit Log, Product Event Log, Fabric Log, FICON Log, Product Status Log, Security Log, Syslog Log. Fabric Watch, MAPS, Bottleneck Detection, and Port Fencing alerts will process like other alerts in the environment. They can be found in the IBM Network Advisor Master Log.
Weekly Backup Switches
Collect a set of configuration files in case they are required to restore the switch configuration. See Switch Backup and Restore section for how to do this
Collect Supportsaves
Collect a complete set of supportsave files from all switches before clearing the switch counters. This will provide a set of switch logs from before the counters were cleared in case they are required for PD. Provides a set of switch logs which can be used a baseline. See Supportsave Scheduled Collection.
Clear Switch Counters
Counters that are never cleared are hard to troubleshoot, and you have no frame of reference for when the error counters on ports actually increased. For this reason the Brocade best practice is to clear the counters on a known schedule, so that error counters seen are known to represent recent issues.
NOTE: Any time new devices are added to the SAN or cabling changes are made, it is common for ports to detect error. These errors should be cleared any time fabric changes are made. Action
Automate a counter clear on all switches that runs on Sunday evening (suggest 6PM local time). You want this to happen after all the normally scheduled weekend changes should be complete and prior to production Sunday night / Monday morning workloads beginning to hit the production system.

IBM Network Advisor Deployment and Best Practices Guide
Monthly Review switch logs for marginal links or other potential switch issues. The following metrics are some of the key metrics when reviewing supportsave files. PORTERRSHOW c3timeout / disc c3
Frame discards are caused because frames are sitting in the frame buffers too long indicating that there are issues sending the frames.
Tx discards are frames that cannot be sent to the attached device, check for link issues then check the attached device
Note: On older switch code levels a portstatsshow for any port with C3 discards may be required to determine if the discards are tx vs rx
rx discards are frames that cannot be sent to the next hop in the switch. Check to see if other ports on the switch have tx discards. Check using framelog command to determine destination for rx frame discards.
crc_err
This counter is incremented when a frame with bad crc passes through the port.
Need to determine where the source of the crc error occurred by check other ports and another switches for crc g_eof errors.
crc g_eof
This counter is incremented when a frame is detected was a crc error. This is the first port to detect the crc error.
Typically caused by an optical issue often cables. Check cables, possible replace or swap the cables. Replace optics (HBA, SFP) on the attached device.
too shrt too long bad eof
Indication of frame errors.
Typically caused by an optical issue often cables. Check cables, possible replace or swap the cables.
loss sync loss sign
Loss of sync and loss of signal typically occur when the optical link cycles usually at the attached device.
Typically no actions are required unless counts are extremely high or occur during unexpected times.
SFPSHOW The primary metric is Rx power which shows the amount of light the SFP is receiving. Typically SFPs transmit around -2 to -3db (630 to 400uwatt) so for short distance cables receive power levels should be similar. Longer cables lengths will result in lower receive light levels and is not consider an issue. In general receive levels should not drop below -10db (100uwatt) unless it’s an extremely long cable run. In general you should compare light levels to other cable runs of similar length and if you have noticeably lower levels compare to the other cables would indicate a cabling issue. ERRDUMP The errdump log should be reviewed for messages that indicate issues which can vary from CDR-xxxx and C2-xxxx, C3-xxxx messages indicating credit loss, to issues show excessive network login attempts to switch hardware issues. FABRICLOG Check the fabric log for signs of ports doing repeated Link Resets, ports going offline/online or repeated fabric rebuilds. Document: Title:

http://www.brocade.com/downloads/documents/product_manuals/NetworkAdvisor/Net workAdvisor_InstallGd_v1230.pdf Additional Requirements We want to do everything we can to eliminate issues in the SAN from impacting our management interface. Should the SAN experience an unexpected degradation or failure, we need to ensure our ability to access Network Advisor is unaffected. This ability could be severely compromised or lost if our main tools (OS, application) reside on the SAN. Therefore, the following points must be followed in performing a best practice installation of IBM Network Advisor server:
Dedicated / Stand-alone server
NOTE: A Virtualized server may be used, however it must follow same requirements as a dedicated/stand-alone server
The server must be dedicated for Network Advisor No other applications installed/running
The server OS must not boot from SAN Install OS on local disk (internal to server)
Network Advisor must not be installed on SAN Install Network Advisor Server/DB on local disk (internal to server)
Server should be partitioned for three drives: one for the OS, one for the Application, and one for Backup Data Backup Data needs to be on physically separate drive

Server and Client Ports The Management application has two parts: the Server and the Client. The Server is installed on one machine and stores device-related information; it does not have a user interface. To view information through a user interface, you must log in to the Server through a Client. The Server and Clients may reside on the same machine, or on separate machines. In some cases, a network may utilize virtual private network (VPN) or firewall technology, which can prohibit communication between Switches and the Servers or Clients. In other words, a Server or Client can find a Switch which appears to log in, but is immediately logged out because the Switch cannot reach the Server or Client. To resolve this issue, check to determine if the ports in the table below need to be opened up in the firewall.

IBM Network Advisor Deployment and Best Practices Guide 1 Port is not configurable (either in the switch or the Management server). 2 Every FTP session requires an additional port which is randomly picked. If the firewall is enabled then FTP operation (used for firmware download, technical support, firmware import (from client-server) and so on.) will fail. 3 Ports configurable in the switch and the Management server. Port must be the same for all switches managed by the Management server. 4 Ports used to launch the Web Tools application for Fabric OS switches from the Management client. This is applicable only when the Fabric OS version is earlier than 6.1.1. 5 Port used for SSL communication. If SSL is enabled, you must open 443*, 24604, and 24605 in the firewall. If SSL is not enabled, port 80* must be open in the firewall and 443*, 24604, and 24605 can be closed. An asterisk (*) denotes the default web server port number. If you set the web server port number to a port other than the default, you must open that port in the firewall. 6 The Syslog listening port is configurable in the Management server. The switch always sends syslog messages to port 514. If you have any other syslog daemon on the Management server machine already listening to 514, then the Management Server can be configured to listen to a different port. You must manually configure relay in existing syslogd to forward the syslog messages to the Management Server listening on the configured port. 7 Ports used for communicating with M-EOSn (M-i10K) directors. M-i10K always uses NMRU over SSL (2049). M-i10K always uses 8080 for http requests (firmware download, configuration backup/ restore, data collection). If M-EOSn firmware version is less than 9.1 the Management application uses 8080 for XMLRPC requests (discovery and asset collection). If the M-EOSn firmware version is more than 9.1 then it always uses SSL port (4430) for XML-RPC. 8 Port must be opened in firewall for the server when the remote ODBC client needs to talk to the Management database server (Only for EE). The same port is used by the Management server to database server (local). This is not used by the Management client. 9 Ports used for communicating with M-EOS (excluding M-i10K) switches (only required when the Management server manages M-EOS switches). 10 Port should be opened in firewall in the Management client to allow communication between server and client (only applicable for M-EOS switches). If this port is not opened in the firewall, then the M-EOS element manager does not receive updates. Also if multiple clients are opened, it will try to use the next available port (55556). So if there are n clients opened in the same machine then you must open 55555 (configurable) to 55555 + n ports in the firewall. 11 The Management server tries to find a contiguous block of 16 ports from the starting port configured (for example, 24600); if any port in this range is not available for the Management application, then you must provide a new starting port. Note that Port 1 to Port 15 in “Ports” column of the table above are not separately configurable and those ports vary based on the starting port number configuration (specified as Port 0 in the above table). The port numbers mentioned in the table above are the default ports (for example, when 24600 is selected as the starting port number).

User Account Management Centralized authentication is IBM best practice in managing user accounts. Regardless of which method of authentication you use (Radius, TACACS+, LDAP, local) you will need to work with your security team to ensure you are meeting the account and IBM requirements. ITCS104 The ITCS104 Technical Security Standards for SAN Switches may be found here. User Management IBM Network Advisor provides a thorough role-based access control (RBAC) feature to define detailed roles and privileges for SAN administrators per the below.
Provides current authentication and authorization configuration details Consolidated list of user profiles, roles, and areas of responsibility (AOR) Provisions to add, modify, duplicate a user profile, role, and AORs Account State column shows active or lock out reasons Access restricted to user assigned with “User Management” privilege with Read-Only/Read-Write permission. No limit for number users added to Brocade Network Advisor. Number of users is dependent on the data base storage limit. Local authentication (local password database), Windows domain login, LDAP, RADIUS, and TACACS+ are supported. Automatic failover to a secondary authentication method can be configured, in case a remote primary authentication method becomes unavailable. Privileges: Provide access to the features in Management application. Role: Group of selected privileges. A role can be assigned to one or more Management application users who need access to the same menu options. AOR (Areas of Responsibility): Used to define device access permission to a user. AORs have the ability to group fabrics, hosts, and other products. AORs can be modified, deleted, or duplicated.
Default and User-defined Accounts In addition to the default accounts—root, factory, admin, and user—Fabric OS supports up to 252 additional userdefined accounts in each logical switch (domain). These accounts expand your ability to track account access and Document: Title:

IBM Network Advisor Deployment and Best Practices Guide audit administrative activities. See the Fabric OS Administrator’s Guide below for in-depth detail on setting up these accounts. NOTE: The default user accounts (root, factory, admin, and user) need to be properly secured. Change the default passwords for root and factory and keep these separate and secure. The root and factory accounts provide a level of access beyond the admin account.
Work with your security team in securing and managing the Root and Factory accounts Work with your security team to define non-default Admin and User accounts with the same access for your users Disable the default Admin and User accounts
AAA (Authentication, Authorization, and Accounting) Settings The Authentication function enables you to configure an authentication server and establish authentication policies. Authentication is configured to the local database by default. If you configure primary authentication to a Radius server, a TACACS+ server, an LDAP server, or switch authentication, you can also configure secondary authentication to the local server. When you log in to the Management application, if the primary server is unavailable, the Management application attempts with the next configured primary server. If all primary servers are unavailable, the Management application falls back to the secondary authentication. Fall back can occur when the server is unavailable, authentication fails, or the user is not found. Configuring authentication may be performed through the Network Advisor Server Management Console. See the Server Management Console section of the Network Advisor User Manual for details on setting up Radius, TACACS+, LDAP, etc. authentication methods.
Server Management Console The Server Management Console (Start > Programs > IBM Network Advisor 11.1.x > Server Management Console) may be used to restart services, change port settings, restore data, and upload technical support information. We will go through a few of these in the screenshots that follow...

Backup and Restore Configuration Data Switch Backup and Restore Saving switch configurations Save switch configuration is only supported on Fabric OS switches. To save switch configuration on more than one switch at a time, you must have the Enhanced Group Management license. Configuration files are uploaded from the selected switches and stored in individual files. Files are named with the convention cfg_fabricName_switchName_domainID.
Select Configure > Configuration > Save. The Save Switch Configurations dialog box displays.
Select the switches for which you want to save configuration files from Available Switches.
Click the right arrow to move the selected switches to Selected Switches.
Click OK. Configuration files from the selected switches are saved to the repository.
Restoring a switch configuration for a selected device Document: Title:
Global Storage Service Line Process IBM Network Advisor Deployment Guide Page 33 of 94
Date: August, 2014 Version: 3.8
IBM Network Advisor Deployment and Best Practices Guide The Restore Switch Configuration dialog box enables you to download a previously saved switch configuration to a selected device. Stored configurations are linked to the switch WWN; therefore, if the IP address or switch name is changed and then rediscovered, the Switch Configuration Repository dialog box displays the new switch name and IP address for the old configuration. If you delete a fabric or switch from discovery, the configuration remains in the repository until you delete it manually. 1. Right-click a device in the Product List or the Connectivity Map, and select Configuration > Configuration Repository. The Switch Configuration Repository dialog box displays.
2. Select the configuration you want to restore, and click Restore. The configuration is downloaded to the device. If necessary, the restoration process prompts you to disable and reboot the device before the configuration begins. This lets you determine whether the configuration backup should be performed immediately or at a later time. If you confirm the restoration, the entire configuration is restored; you cannot perform selective download for specific configuration sections.
Scheduling Switch Backups The Enhanced Group Management (EGM) license must be activated on a switch to perform this procedure and to use the supportSave module. If a periodic backup is scheduled at the SAN level, that backup will apply to all switches from all discovered fabrics. Any new fabrics being discovered are automatically added to the list of fabrics to be backed up. If a backup is scheduled for more than one fabric and some of the fabrics contain common members, the backup will include the unique switch configuration values obtained from the fabrics. You can schedule a backup of one or more switch configurations. The configuration files are stored in the Management application database. Document: Title:

Server Data Backup and Restore Network Advisor helps you protect your data by backing it up automatically. The data can then be restored as necessary. What is backed up? If we set our backup for the D:\ drive (or whatever the backup drive is) the following files/data will reside in D:\Backup, as follows:
Backup\databases — contains database and log files. Backup\data — contains M-EOS switches Element Manager data files (including Dump files, Data collection progress files, Director/Switch firmware files FAF files, Switch technical SupportSave, and Switch backup files) and Fabric OS miscellaneous files. Backup\conf – contains the Management application configuration files. Backup\cimom – contains the SMIA configuration files.
Configuring backup to a hard drive NOTE: This requires a hard drive. The drive should not be the same physical drive on which the Operating System or the Management application is installed. To configure the backup function to a hard drive, complete the following steps (screenshot below for reference).
Select Server > Options. The Options dialog box displays.
Select Server Backup in the Category list. The currently defined directory displays in the Backup Output Directory field.
Select the Enable Backup check box, if necessary.
Choose the following option:
Select the Include FTP Root directory check box. In selecting the FTP Root directory, the FTP Root sub-directories, Technical Support and Trace Dump, are selected automatically and you cannot clear the sub-directory selections.
Enter the time (using a 24-hour clock) you want the backup process to begin in the Next Backup Start Time Hours and Minutes fields.
Select an interval from the Backup Interval drop-down list to set how often backup occurs.
Browse to the hard drive and directory to which you want to back up your data (this should be a separate physical drive).
Click Apply or OK. The application verifies that the backup device exists and that the server can write to it. If the device does not exist or is not writable, an error message displays that states you have entered an invalid device. Click OK to go back to the Options dialog box and fix the error. Backup occurs, if needed, at the interval you specified.

Fabric Watch Fabric Watch tracks a variety of SAN fabric elements and events. Monitoring fabric-wide events, ports, and, environmental parameters to enable early fault detection via SNMP.
Reasons to Implement Fabric Watch IBM in general has not been manually monitoring for error conditions within our SAN environments to date and this has led to multiple customer impacts that could have been easily avoided.
Fabric Watch can be enabled and thresholds set to alert on these events for code level 6.3 and above.
Fabric Watch specific alerts to be enabled are documented below.
Fabric Watch should have been purchased with the switch (it is a FOS feature, and is included automatically with all Brocade SAN switches purchased from IBM).
When configuring Fabric Watch, the Fabric/Port Class and Alert Type/Threshold settings below should be followed:

Bottleneck Credit Tools The bottleneck credit tool is used to automatically reset back end ports when loss of credits is detected on the back end ports. This function was introduced in Brocade FOS v7.0.0 and v6.4.2 and was further enhanced with improved credit loss detection in FOS v7.0.1b and v6.4.3
Enabling bottleneck credit tools Use the --cfgcredittools commands to enable or disable credit recovery of back-end ports, and use the --showcredittools parameter to display the configuration. When this feature is enabled, credit is recovered on back-end ports (ports connected to the core blade or core blade back-end ports) when credit loss is detected on these ports. If complete loss of credit on a Condor 2 back-end port causes frame timeouts, an LR is performed on that port regardless of the configured setting, even if that setting is -recover off. When used with the -recover onLrOnly option, the recovery mechanism takes the following escalating actions: When the mechanism detects credit loss, it performs an LR and logs a RASlog message (CX-1014). If the LR fails to recover the port, the port reinitializes. A RASlog message is generated (CX-1015). Note that the port reinitialization does not fault the blade. If the port fails to reinitialize, the port is faulted. A RASlog message (RAS CX-1016) is generated. If a port is faulted, and there are no more online back-end ports in the trunk, the port blade is faulted. A RASlog message (RAS CX-1017) is generated. Enable credit recovery tool with the LROnly option.

Bottleneck Detection As transmission speeds within SAN fabrics continue to increase devices causing latency within the fabric have a larger impact on the overall health of the fabric. Devices causing latency have caused multiple customer impacts within IBM. Bottleneck Detection now provides a way to automatically watch for and alert upon high latency devices. This ability has already proven to shorten environment impact times within IBM operated environments from days to hours.
Recommendations
Field experience shows that the original strategy of enabling Bottleneck Detection with conservative values for latency thresholds almost always yields no results. There was a concern that aggressive values would result in Bottleneck Detection alert storms, but this has not been the case. Even the most aggressive values result in relatively few alerts being generated. As a result, it is now recommended that the most aggressive settings are tried first and then backed off gradually if too many alerts are seen.
Brocade 48000 should have no more than 100 ports monitored due to memory constraints
Congestion Threshold (-cthresh): Is new starting with code level 6.4. This monitors bandwidth utilization, the percentage of time that a link exceeds 95% utilization. The recommendation is to stay with the Brocade default value for this setting (80%). This means that if an individual link exceeds 95% utilization for 80+% of the measurement interval (the –time specification= 30 seconds) an alert will be sent.
Latency Threshold (-lthresh): This is the minimum percent of time when a latency is detected (default is 20% or .2) This is the parameter we will adjust as we fine-tune BD
Window: Specifies the measurement interval for measuring latency
Quiet Time: Specifies how often to send any tripped alerts

How Bottlenecks are reported in Network Advisor Bottlenecks are reported through alerts in the Master Log. A bottleneck cleared alert is sent when the bottleneck is cleared. NOTE: A bottleneck cleared alert is sent if you disable bottleneck detection on a bottlenecked port, even though the port is still bottlenecked. Bottlenecks can be highlighted in the Connectivity Map and Product List. Select Monitor > Performance > View Bottlenecks. If a port is experiencing a bottleneck, a bottleneck icon is displayed in the Connectivity Map for the switch and fabric, and in the Product List for the port, switch, and fabrc. In the figure below, port15 and port22 are bottlenecked.

Port Fencing Reasons to Implement Port Fencing As transmission speeds within SAN fabrics continue to increase, devices causing latency within the fabric have a larger impact on the overall health of the fabric. The health of the fabric may degrade faster than an alert can be sent, received by the monitoring team, support tickets opened, and the required manual action to protect the fabric be taken. Port Fencing provides a way to have the fabric respond to error-level thresholds by disabling port with high error rates. It sends an alert that this action has been taken so the steady state team can repair the situation and then bring the port back online.
Implementation NOTE: Port Fencing should only be done after the environment has successfully implemented Fabric Watch using the settings recommended in this guide. Healthy SAN fabrics are a prerequisite to implementation of Port Fencing. DO NOT implement Port Fencing unless the following criteria are met:
The environment is running code level 7.0.2c or newer. . In code levels prior to 7.0.2c, the FW-1510 alert sent by the switch to inform administrators that Port Fencing has disabled ports is at an “Informational” severity level. This alert severity has been raised to “Error” in the 7.0.2c release. The monitoring or steady state team has the cycles to monitor “Informational” SNMP alerts from the SAN switches. A mature SNMP monitoring and response process must be in place prior to implementation of Port Fencing. Port Fencing is going to disable ports, a steady state team must receive these alerts and take action to fix the port and bring it back online. Failure to ever take action will result in future Client Impacting Events.
Example: 1 of 2 SAN ports for a server exceeds the Port Fencing threshold and the port is automatically disabled by the SAN switch. The steady state team does not repair the port and bring it back online. A month later the remaining HBA in the server fails, now the server has no connectivity to back-end SAN storage devices. When configuring Port Fencing within FOS v6.4.2a, the Violation Type and Threshold settings below should be followed:
E Port Class Area (note: the Time Base for all Alerts = 1 minute) Violation Type Protocol Error Link Reset Invalid Words (enc out) Invalid CRCs
Threshold 10 10 60 30

Monitoring and Alerting Policy Suite (MAPS) The Monitoring and Alerting Policy Suite (MAPS) is a storage area network (SAN) health monitor supported on all switches running Fabric OS 7.2.0 or later. This will replace Fabric Watch as the default health monitor once the FOS is at v7.2.0 or later. MAPS allows you to enable each switch to constantly monitor itself for potential faults and automatically alerts you to problems before they become failures. It is recommend setting up MAPs and not migrating the Fabric Watch settings, unless Fabric Watch was setup for a specific reason. See Initial MAPS setup
MAPS Licensing Requirements and Software Prerequisites Switches with Fabric Watch and Advanced Performance Monitor licenses automatically get the Fabric Vision license features by upgrading to FOS v7.2 Switches with only Fabric Watch or Advanced Performance Monitor can upgrade to Fabric Vision by purchasing other license (either Fabric Watch or Advanced Performance Monitor license). MAPS Software Prerequisites: FOS Version: v7.2.0d IBM Network Advisor: 12.13 or higher. NOTE: MAPS is the follow-on product to Fabric Watch, and while both require a license Fabric Watch customers can upgrade to MAPS without additional cost. If the switch currently has Fabric Watch setup and properly monitoring the fabric those Fabric Watch settings can be migrated to MAPS rules.

Converting from Fabric Watch to MAPS 1. Backup the switch configuration using configupload 2. Use the maspconfig –fwconvert to convert Fabric Watch rules to MAPS.If Fabric Watch is currently in use this needs to be done before enabling MAPS, to preserve the Fabric Watch thresholds. Three new maps policies are create fw_active_policy based on the Fabric Watch settings currently active, fw_defaut_policy based on the Fabric Watch default settings and fw_custom_policy based on any Fabric Watch custom policies that were created. 3. The conversion is one way, you cannot convert MAPS rules back to Fabric Watch 4. The first time you enable MAPS, using the command mapsconfig --enablemaps -policy fw_active_policy you will receive a warning (screenshot of the same given below).
5. Set allowable actions for rules using mapsconfig --actions raslog, snmp, email, sw_critical, sw_marginal, sfp_marginal Make sure port fencing is not enabled / included in the mapsconfig command.
Initial MAPS setup For switches running FOS 7.2 or higher and that do not have Fabric Watch currently configured to monitor and alert for fabric events or if a clean MAPS setup is required use the following procedure The recommended port monitoring strategy is to log marginal port events to the RAS log which should be reviewed on a regular bases, and to generate SNMP or email alerts for serious port events that need immediate attention. Note: To implement this policy you can simply import the IBM_SO policy see Importing MAPS configuration Since the MAPS default policies generate SNMP / email alerts for all of their port events the strategy is to copy the default policy as a base, but to replace the port rules with rules that implement the above strategy based on the settings defined for Fabric Watch.
1. Create a copy of the MAPS default moderate policy as a base
mapspolicy --clone dflt_moderate_policy -name IBM_SO
2. Remove the port rules from the policy using the following commands. Note: Must be run from root
for i in $(mapspolicy --show IBM_SO | grep defNON | awk '{print $1}'); do mapspolicy --delrule IBM_RTS -rulename $i; done
for i in $(mapspolicy --show IBM_SO | grep E_PORTS | awk '{print $1}'); do mapspolicy --delrule IBM_RTS -rulename $i; done

for i in $(mapspolicy --show IBM_SO | grep T_PORTS | awk '{print $1}'); do mapspolicy --delrule IBM_RTS -rulename $i; done
mapspolicy --delrule IBM_SO -rulename defSWITCHSEC_TS_D10
3. Create new F-Port rules for the new IBM_SO policy
mapsRule --create F_PORTS_PE_5 -group ALL_F_PORTS -timebase min -op g -policy IBM_SO -monitor PE -value 5 -action RASLOG
mapsRule --create F_PORTS_ITW_25 -group ALL_F_PORTS -timebase min -op g -policy IBM_SO -monitor ITW -value 25 -action RASLOG

Network Advisor Dashboards The below IBM Network Advisor Dashboard Widgets, Event Logs, and SAN Health are great tools for doing everything from quick assessments to in-depth investigation of the overall health of your SAN. Dashboard Tab- at a glance The Dashboard tab provides a high-level overview of the network and the current states of managed devices. This allows you to easily check the status of the devices on the network. The dashboard also provides several features to help you quickly access reports, device configuration, and system logs. The dashboard updates every 5 seconds regardless of the currently selected tab (SAN or Dashboard) or the SAN size. However, data may become momentarily out of sync between the dashboard and other areas of the application. For example, if you remove a product from the network while another user navigates from the dashboard to a more detailed view of the product, the product may not appear in the detailed view.
The Dashboard includes the following widgets: 1. SAN Operational Status. Displays the device status as a pie chart. Displays the device status as a percentage of the total number of devices. Displays the percentage in various colors on each slice. Displays the color legend below the pie chart. Displays tooltips on mouse-over to show the number of devices in that state. When there is one status category with less than one percent of the total number of devices, the status widget displays the number of devices in each category on each slice. 2. SAN Inventory. Displays the SAN products inventory as stacked bar graphs. Displays each group as a separate bar on the graph. Displays the current state of all products discovered for a group in various colors on each bar. Displays the color legend below the y-axis. Displays tooltips on mouse-over to show the number of devices in that state. 3. Events. Displays the number of events by severity level for a specified time range as a stacked bar graph. You can customize this widget to display a specific time range. Options include: This Hour, Last Hour, Last 24 Hours, Last 7 days, or Last 30 Days

Brocade SAN Health Report SAN Health is a powerful (and free) utility from Brocade for surveying your SAN. SAN Health should be run at least on a monthly basis, doing so will help you recognize trends in your environment, as well as unknown current or potential issues. Performing and maintaining regular sets of SAN Health reports can also aid in troubleshooting, as they provide you with a detailed history of events taking place in your SAN.
You can download this utility and instructions for using it from Brocade at: www.brocade.com/sanhealth
Brocade SAN Health reports contain information such as the following:
Fabric level information total port count, performance, oversubscription ratios, port utilization, and number of attached devices followed by specific information on each fabric, such as the connected switches, zoning configuration, and a port map.
Switch level information such as licenses, port level configurations and ISL usage.
Port level information such as bandwidth utilization, CRC counts and port status provides a snapshot on overall port health.
Visio diagram shows the logical connection of the switches in the fabrics as well as the connected devices. ISLs, trunks and devices are shown exactly how they are connected to the switch ports. From this diagram, the fabric topology and other information can be viewed quickly and easily.
Customized views of devices allow for online device identification, snapshot of performance stats and switch attachment details.
Other items in this report include historical performance graphs plus guidelines and recommendations.
NOTE: Past reports should be saved for trend and troubleshooting and planning purposes. These reports can be very helpful when trying to identify the source of an issue and should be readily available for “Crit-Sit” and Sev-1 types of situations.

Zoning All zoning tasks must be performed from the Zoning dialog box in the Network Advisor application. You can access the Zoning dialog box from the main screen of the Management application using any of the following methods:
Select Configure > Zoning > Fabric. Click the Zoning icon on the toolbar. Right-click a port, a switch, a switch group, or fabric in the device list and select Zoning. Right-click a port, a switch, a switch group, or fabric in the Connectivity Map and select Zoning.
NOTE: The following points need to be observed when performing zoning operations
Zoning via the CLI or Web Tools interface should never be performed due to the increased potential for catastrophic customer-impacting mistakes associated with these methods.
“Single-Initiator Zoning” should be used for all zoning. A single-initiator zone contains one HBA in a zone with target device/s.
Your default zoning mode should be set for “No Access”. This means unzoned devices cannot see each other and therefore requires a zone be established before they can communicate
The following is a procedure for zoning in a Brocade Fabric using IBM Network Advisor and will assure the following:
The current zone configuration in the fabric will be saved to the Network Advisor offline repository and can be restored to the fabric if necessary.
Multiple copies of the fabric zoning configuration will be stored in the offline repository. The number of copies will be dependent on your policy for cleaning out old zone DB copies in the offline repository.
The offline repository will be backed up as part of the scheduled Network Advisor backup when that backup occurs. There will be exposure to lost updates to the zoning DB’s should the Network Advisor server become unavailable and have to be restored. The updates from the time of the last backup until the time the server is lost would be unrecoverable.
The current active Fabric Zone DB will always be the zoning DB used for updating when zoning changes are necessary in the fabric. The offline repository zone DB’s will only be used for recovery if necessary.
The following will demonstrate the steps necessary to make changes to the current zone configuration and assure a copy of the current zone DB is stored to the offline repository as a fallback if necessary. The current Fabric Zone DB consists of only 1 zone configuration.

A request has come in to add an additional zone to the fabric, we will add this zone as zone4. Updates to fabric zoning will always be made to the current active zone configuration in the Fabric Zone DB. To assure that the Network Advisor zoning configuration window is current and assure you are viewing what is currently active in the fabric, perform a Zone DB Operation to refresh the DB. Verify the Zone DB listed is the Fabric Zone DB and perform a refresh. Zone DB Operation Refresh (See below)
