Displaying changes in the MAC table
You can display the complete MAC table, a specific entry in the MAC table, or a specific MAC entry
with M-port details.
To display the complete MAC table, enter the following command.
Brocade# show mac
MAC Address Port Age VLAN Type
0100.5e42.7f40 1/1... Static 10
Ports : e 1/1 to 1/3 e 2/1 to 2/5
0000.999d.9996 2/20 Static 10
To display a specific MAC address from the MAC table, enter the following command.
Brocade# show mac 0100.5e42.7f40

SA and DA learning and aging
Static MAC addresses and multi-port MAC addresses can always be programmed in the CAM of all
LP modules with valid VLAN membership. Multi-port static MAC addresses are added or removed
from the CAM when a port is added to or deleted from a VLAN. These addresses cannot be
dynamically learned or moved to a different port. These addresses will not be removed from the
hardware unless the user deletes the multi-port static MAC addresses.
MP switchover and hitless upgrade
The Multi-port static MAC Address feature supports MP switchover and hitless upgrade.
The static MAC table is maintained on both active and standby MPs. The static MAC table is
synched to standby MP by CLI configuration commands. The M-port table and FID are also synched
from the active MP to the standby MP. After MP switchover, M-port MAC addresses are associated
with the FID and, in the case of a missing FID, a new FID will be created and programmed for the
multi-port static MAC address.
The static MAC table and FID table will be reprogrammed after LP reload.
Flooding features
User-configured multi-port static MAC addresses will always be programmed on DA CAMs in all
PPCR CAMs. So, traffic with this DA MAC address will never be flooded in the VLAN, even when
flooding features like transparent VLAN, unknown unicast flooding, multicast flooding, and CPU
protection are configured on the system.
