Message Stack: Stack is operational due to FAIL-OVER
Explanation Indicates that a failover has occurred.
Message Level Informational
To view the System log or the traps logged on an SNMP trap receiver, enter the show log command at
any level of the CLI. The following example output shows what the log might look like after a switchover
or assignment of the standby controller.

Syslog logging: enabled (0 messages dropped, 1 flushes, 0 overruns)
Buffer logging: level ACDMEINW, 8 messages logged

The following example output shows what the log might look like after a failover of the active controller.
NOTE
In FCX devices after failover, the output of the show log command displays the status of the previous
management port interface.
