Example
The following command displays MSM failover statistics:
show msm-failover
The output displays the following:
•
Current state of the MSM
• Software image information (primary/secondary image, version)
•
Cause of the last failover
• Failover configuration (link action, preserve state, slave configuration, timeout)
•
ESRP failover mode
• Failover status for the supported subsystems (configuration, layer 2 hardware, layer 3 hardware, STP,
EAPS, ARP, ESRP)
Each of the supported subsystems display one of the following states:
— disable—Hitless failover is disabled. This is also the initial state.
— initial—Hitless failover is enabled, but the downloading of the subsystem state has not yet started
for a particular subsystem.
— xfr—The subsystem’s state is in the process of being transferred to the slave. The state transfer
includes all of the state for that subsystem.
—
ready—The subsystem has received its state download. In the ready state, it may receive updates
to its internal states.
— failed—The subsystem encountered a failure. To clear the failure, reboot the slave MSM.
