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.
