When executing an upgrade onto , engineering teams should be aware of known platform behaviors documented within the extended maintenance train:
If you intend to use to prevent link downtime
When running dual Supervisor Engines in a single chassis, this binary handles synchronized clustering perfectly. It utilizes and Stateful Switchover (SSO) . If the primary supervisor fails, the secondary engine assumes operations in milliseconds without dropping established routing protocol peerings.
