An RPR+ switchover does not involve resetting line cards or reloading line card software for VIPs. Hi, As @Leo Laohoo mentioned, you have to use the command ----Redundancy force switchover. I reloaded the switch A again: same behavior, it was stuck on recovery mode. IPSec tunnel states are synchronized between the master and standby chassis. If you issue the reload command and the status is not standby hot, the reload command will reset the current supervisor engine only. Due to the software version mismatch between the two chassis, the VSS standby chassis will be in RPR redundancy mode. In role switching, the mirror server acts as the failover partner for the principal server, taking over the principal role, recovering its copy of the database. You can verify the state with the show redundancy command. Supervisor Engine Synchronization Because the standby supervisor engine is not fully initialized, it interacts with the active supervisor engine only to receive configuration changes as they occur, keeping the configuration information on both supervisor engines. Thus, when a system failure occurs, there is another system that serves as a backup. For option #2, it is recommended that the license for the Secondary WLC be the same as the. Cisco 7600 series routers support fault resistance by allowing a redundant supervisor engine to take over if the primary supervisor engine fails. Redundancy, as the name may suggest, is the duplication of unit systems in a data center. Forcing a Switchover. The redundancy force-switchover command will first check that the redundant supervisor engine is in the correct state. Enter the command redundancy force-switchover. 150. Software. 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. Same-zone HA: This option provide for infrastructure redundancy with lower network latency because the primary and standby servers will be in the same availability zone. This will move the active role to the other switch with very.
