Reviving a Cisco SME Cluster

displayed by the show sme cluster detail command. Reviving the cluster on a switch that does not have
the highest configuration version can lead to data corruption.
The following procedure assumes that switch1 has the latest SME configuration version. The steps

cluster.
On switch2, shut down the cluster by performing this task:
