The standby Supervisor or the active Supervisor may be impacted, even reloaded. If there is release mismatch, when inserting the standby Supervisor, either Hardware Compatibility Matrix for the Cisco cBR Series RoutersĬisco IOS-XE Release 16.5.1 and Later Releasesīoth Supervisors must be running identical software releases.

The Feature Information Table at the end of thisĭocument provides information about the documented features and lists the releases in which each feature is supported. For the latest feature informationĪnd caveats, see the release notes for your platform and software release. Your software release may not support all the features that are documented in this module. If a fatal error occurs on the active Supervisor, the system immediately switches to the standby Supervisor. When you configure Supervisor Redundancy, the standby Supervisor is synchronized with the active Supervisor. It enables a quicker switchover between active and standby Supervisors when a fatal error occurs on the active Supervisor. The Supervisor Redundancy feature reduces unplanned downtime.
