High Availability (Ha); Patch Flash://Runtime_Patch_Dir - Dell S4810 Reference Manual

High Availability (HA)

High availability (HA) in the Dell Networking operating software is configuration synchronization to
minimize recovery time in the event of a route processor module (RPM) failure. The feature is available on
the S4810 platform.
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, the redundancy protocol command).
