Management module redundancy configuration

When the system is powered on or otherwise reset normally, the system sends a cold start message and trap. However, if the system is
reset as the result of switchover to the standby management module, the system instead sends a warm start message and trap.
MAC address changes
The MAC addresses in the system are based on the MAC address of the chassis. During switchover, the system's MAC addresses do not
change.
Management module redundancy configuration
Configuring management module redundancy consists of performing one optional task (changing the default active chassis slot). The
following section explains how to perform this task.

Changing the default active chassis slot

By default, the system considers the module installed in the lower-numbered slot to be the active management module. If desired, you
can change the default active chassis slot to the higher-numbered slot.
To change the default active chassis slot, enter commands such as the following.
device# configure terminal
Brocade(config)# set-active-mgmt mgmt1
Syntax: [no] set-active-mgmt { mgmt0 | mgmt1 }
mgmt0 is the lower-numbered slot and mgmt1 is the higher-numbered slot.
To remove the configuration, use the no form of the command. You cannot use the erase startup command to remove the configuration.
To view the default active chassis slot currently configured on the device, use the show run command.

Managing management module redundancy

The FSX 800 and FSX 1600 support the following management tasks related to management module redundancy:
• Perform immediate synchronization of files
• Perform a manual switchover to the standby module
• Reboot the standby module
File synchronization between the active and standby management
modules
Each active and standby management module contains the following files that can be synchronized between the two modules:
• Flash code - The flash code can include the following files:
– Primary - Contains the management module's primary IronWare image.
– Secondary - Contains the management module's secondary IronWare image.
The primary and secondary files also include a monitor file, which contains the management module's Real Time Operating System
(RTOS).
