How to Enable Cisco WLC 9800 Standby console.

Access to the Standby chassis:

Please follow the below step.

Console access to the Standby chassis is not available by default. The console displays the following error message:

9800_WLC stby>?

Standby console disabled

When the HA pair is established, configuration commands can only be executed on the Active chassis.

However, the Standby console can be enabled using the following command on the Active chassis:

9800_WLC(config)# redundancy

9800_WLC(config-red)# main-cpu

9800_WLC(config-r-mc)# standby console enable

The Standby console then provides a restricted set of commands, mostly "show" commands.
