Configuring a redundant management module

In a ServerIron ADX chassis that contains a redundant Management module,

You can install a redundant management module in a ServerIron ADX chassis. (By default, the

system considers the module in the lower slot number to be the active management module and

the other module to be the redundant, or standby module. If the active module becomes

unavailable, the standby module automatically takes over management of the system. You can

however override the default and make the redundant Management module in the higher slot

number the default active module.

NOTE

This feature only applies for chassis-based ServerIron ADX switches that are equipped with

redundant Management module.

To change the active management module in a ServerIron ADX chassis to the module in the higher

slot number, use the following command.

ServerIronADX(config)# redundancy

ServerIronADX(config-redundancy)# active-management 2

ServerIronADX(config-redundancy)# exit

ServerIronADX(config)# exit

ServerIronADX# write-memory

ServerIronADX# reload

Syntax: [no] active-management <module-number>

The <module-number> variable specifies the management module that will assume Active

management upon reboot of the ServerIron ADX switch. You can specify 1 or 2. If you specify 1, the

default Management module will be active. If you specify 2, the redundant Management module in

the higher slot number will be the Active module after reboot.

NOTE

The change in active Management module does not take effect until you reload the switch. If you

save the change to the active module’s system-config file before reloading, the change persists

across system reloads. Otherwise, the change affects only the next system reload.

Synchronizing the active and standby modules

You can immediately synchronize software between the active and standby management modules.

When you synchronize software, the active module copies the software you specify to the standby

module, replacing the software on the standby module.

To immediately synchronize the configuration data (in flash memory or flash module) on the

standby module with the configuration data on the active module, enter the following command.

ServerIronADX# sync-standby config

To immediately synchronize the flash image code (system software) on the standby module with

the code image on the active module (in flash memory or flash module), enter the following

command.

ServerIronADX# sync-standby code

To immediately synchronize the SSL keys and certificates on the standby module with the SSL keys

and certificates on the active module, enter the following command.
