Mac cache

Fast MAC cache failover

When an uplink that was in standby mode becomes active, it can take several minutes for external Ethernet interconnects to recognize that the server blades can now be reached on this newly active connection.

Enabling Fast MAC cache failover causes Ethernet packets to be transmitted on the newly active connection, which enables the external Ethernet interconnects to identify the new connection (and update their MAC caches).

The transmission sequence is repeated a few times at the MAC refresh interval and completes in about 1 minute.

Default value:

Enabled

MAC refresh interval

Time interval at which MAC caches are refreshed is 5 seconds.
