Usage Guidelines

Any switchover function is nonrevertive. Once a switchover has occurred and the failed processor has

been replaced or successfully restarted, you cannot switch back to the original, active supervisor module

(unless there is a subsequent failure or you issue the system switchover command).

The following example initiates a HA switchover from an active supervisor module to a standby

supervisor module.
