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
