Reassigning the Cisco SME Cluster Master Switch
To reassign the master switch assignment to another switch, use these procedures. This will change the
master switch assignment from one switch to another switch. For information on the master switch
election, see the
“Cluster Quorum and Master Switch Election Overview” section on page 4-30.
Caution This procedure is disruptive and it will shut down Cisco SME during this change.

new master switch.
On all switches other than switch1 and switch2, shut down the cluster by entering the following
commands. Perform this step for every switch in the cluster other than the current master switch and the
desired new master switch.
