Hitless is a protocol-based system behavior that makes a stack unit failover on the local system transparent to remote systems. The

system synchronizes protocol information on the Management and Standby stack units such that, in the event of a stack unit

failover, it is not necessary to notify the remote systems of a local state change.

Hitless behavior is defined in the context of a stack unit failover only.

Only failovers via the CLI are hitless. The system is not hitless in any other scenario.

Hitless protocols are compatible with other hitless and graceful restart protocols. For example, if hitless open shortest path first

(OSPF) is configured over hitless the link aggregation control protocol (LACP) link aggregation groups (LAGs), both features work
