MAC operations

This section describes MAC related configuration operations

MAC Database Update (MDUP)

The MACs that are learned locally are given the highest priority or the cost of 0 so they are always
selected as best MAC.

Each MAC is advertised with a cost. Low cost MACs are given preference over high cost MACs.

If a MAC moves from a CCEP port to a CEP port, a MAC move message is sent to the peer and the
peer moves the MAC from its CCEP ports to the ICL links.

When peer MACs in a cluster become out of sync for any client, you can recover by performing the
following tasks, which are described in the following sections:

Perform periodic health checks on both peers to determine if the MAC table for any client is out
of sync.

Manually or dynamically synchronize the MAC table.

Display synchronization details using show commands.

Enabling MAC health check

NOTE

Client health check is disabled by default.

To enable client health check for all configured clients in cluster mode, enter the
client-health-check command.

Brocade(config-cluster-TORA)# client-health-check

Syntax: [no] client-health-check

Disabling MAC health check

The no version of the client-health-check command disables the client health check for all
configured clients in cluster mode.

Brocade(config-cluster-TORA)# no client-health-check

Syntax: [no] client-health-check
