Example: Device# show redundancy states: Displays the operating redundancy mode. 3. The Virtual Router Redundancy Protocol (VRRP) feature can solve the static configuration problem. • If the higher priority switch is currently in VSS standby state, you can make it the VSS active switch by initiating a switchover. This is known as a database switchover or failover. The Multichassis Link Aggregation Control Protocol (mLACP) solution addresses the latter, where a carrier wants dual-homed device (DHD) to two upstream points of attachment (PoA) for redundancy. This command initiates a manual cluster failover (see sk55081 ). Router (config-red)# mode rpr. Primary/Secondary is the old method. If you force a switchover from the active PRE, both PREs synchronize and the active PRE reloads normally. During a software upgrade, the networking device appears to be in a mode other than SSO--During the software upgrade process, the show redundancy command indicates that the device is running in a mode other than SSO. Rather than trying to react to the failover on the new primary, I think it would make more sense to update your manual failover procedure to first change the AG to sync mode. In the case of failover, the old primary is offline so there are no options for migrating clients from the old primary to the new primary. The unit will stay in a failover state regardless of the conditions.
