Monitoring management module redundancy
You can monitor the following aspects of management module redundancy:
• The status of the management modules (if a module is the active or standby module)
• The switchover history for the management modules
The following sections explain how you can monitor the management modules
Determining management module status
You can determine the status of a management module in the following ways:
• LEDs - The LEDs on the management module indicate whether a module is the active module or
the standby module, and if the module has power.
• Redundant management and module information in software - The module information displayed
by the software indicates whether a module is the active module or the standby module.
Status LED
If you are located near the chassis, you can determine which management module is currently the
active module and which is the standby module by observing the Active LED on each module. If this
LED is on (green), the module is the active module. If this LED is off, the module is the standby
module.
You can also observe the Pwr LED on each module. If this LED is on (green), the module is receiving
power. If this LED is off, the module is not receiving power. (A module without power will not function
as the active or standby module.)
Software
You can use the show module CLI command to display the status of the management modules.
The following shows an example output of the show module command.

The Status column indicates the module status. The management modules can have one of the
following statuses:
• ACTIVE - The module is currently the active management module.
• STANDBY - The module is the standby management module. The status of the standby module
can be one of the following:
