The following table lists when each platform and management module began supporting hitless failover for a specific protocol.
Hitless failover requires a switch with two MSMs/MMs installed.
Remember, as described in the following table, not all protocols support hitless failover. If you are running an earlier version of ExtremeXOS than that listed in the ExtremeXOS version column, the switch does not support hitless failover for that protocol.
