Dell Command Line Reference Guide for the S4048–ON System


High Availability (HA)

High availability (HA) in the Dell EMC Networking OS is the configuration synchronization to minimize recovery time in the event of a route processor module (RPM) failure.

In general, a protocol is defined as “hitless” in the context of an RPM failure/failover and not failures of a line card, SFM, or power module. A protocol is defined as hitless if an RPM failover has no impact on the protocol.

You must specifically enable some protocols for HA. Some protocols are only hitless if related protocols are also enabled as hitless (for example, using the redundancy protocol command).
