Step 2
| View the current Supervisor redundancy state by running the show redundancy command. The active Supervisor is typically shown in slot 4 (SUP0).Router# show redundancy
Redundant System Information :
------------------------------
Available system uptime = 28 minutes
Switchovers system experienced = 0
Standby failures = 0
Last switchover reason = none
Hardware Mode = Duplex
Configured Redundancy Mode = sso
Operating Redundancy Mode = sso
Maintenance Mode = Disabled
Communications = Up
Current Processor Information :
-------------------------------
Active Location = slot 4
Current Software state = ACTIVE
Uptime in current state = 28 minutes
Image Version = Cisco IOS Software, IOS-XE Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Experimental Version 15.5(20150302:044048) [v155_2_s_xe315_throttle-xxxxx-XE315_0301 121]

If a switchover occurs, the show redundancy command shows that the active Supervisor has changed slots, moving from slot 4 (SUP0) to slot 5 (SUP1). The output is similar to the one in the following example.
Router# show redundancy
Redundant System Information :
------------------------------
Available system uptime = 39 minutes
Switchovers system experienced = 1
Standby failures = 0
Last switchover reason = user forced
Hardware Mode = Duplex
Configured Redundancy Mode = sso
Operating Redundancy Mode = sso
Maintenance Mode = Disabled
Communications = Up
Current Processor Information :
-------------------------------
Active Location = slot 5
Current Software state = ACTIVE
Uptime in current state = 10 minutes
Image Version = Cisco IOS Software, IOS-XE Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Experimental Version 15.5(20150302:044048) [v155_2_s_xe315_throttle-xxxxx-XE315_0301 121]

If the standby Supervisor is not installed or is not operational, the show redundancy command gives an output similar to the following example:
Router# show redundancy
Redundant System Information :
------------------------------
Available system uptime = 31 minutes
Switchovers system experienced = 1
Standby failures = 0
Last switchover reason = user forced
Hardware Mode = Simplex
Configured Redundancy Mode = sso
Operating Redundancy Mode = Non-redundant
Maintenance Mode = Disabled
Communications = Down Reason: Failure
Current Processor Information :
-------------------------------
Active Location = slot 5
Current Software state = ACTIVE
Uptime in current state = 2 minutes

Peer (slot: 4) information is not available because it is in 'DISABLED' state
The show redundancy command shows details of the redundancy state, software state, system uptime, image version, boot, configuration file, and configuration register information.
