What happens when switchover occurs

When a switchover occurs, the features that support nonstop switching continue to operate in an uninterrupted manner. See Nonstop switching features for a list of the supported features.

The features that do not support nonstop switching perform as if the switch had just finished booting; however, no actual boot time occurs.


When meshing configuration changes are made on a redundant management system, you must execute write mem and then the boot system command to boot both management modules for the changes to be activated.

Meshing is not supported by nonstop switching.


If the switch is a querier and a failover occurs, the querier continues to be the same on the standby management module; no new querier election process occurs on the standby management module.
