Configuring the MAC address table

DRAFT: BROCADE CONFIDENTIAL
Configuring the MAC address table
Each CEE port has a MAC address table. The MAC address table stores a number of unicast and 
multicast address entries without flooding any frames. Brocade FCoE hardware has a configurable 
aging timer. If a MAC address remains inactive for a specified number of seconds, it is removed 
from the address table. For detailed information on how the switch handles MAC addresses in a 
Layer 2 Ethernet environment, see 
Specifying or disabling the aging time for MAC addresses
You can set the length of time that a dynamic entry remains in the MAC address table after the 
entry is used or updated. Static address entries are never aged or removed from the table. You can 
also disable the aging time. The default is 300 seconds.
NOTE
To disable the aging time for MAC addresses, enter an aging time value of 0.
To specify an aging time or disable the aging time for MAC addresses, perform the following steps 
from Privileged EXEC mode.
1. Enter the configure terminal command to access global configuration mode. 
2. Enter the appropriate command based on whether you want to specify an aging time or disable 
the aging time for MAC addresses:
switch(config)#mac-address-table aging-time 600
Adding static addresses to the MAC address table
To add a static address to the MAC address table, perform the following steps from Privileged EXEC 
mode.
1. Enter the configure terminal command to access global configuration mode. 
2. Add the static address 0011.2222.3333 to the MAC address table with a packet received on 
VLAN 100:
switch(config)#mac-address-table static 0011.2222.3333 forward 
tengigabitethernet 0/1 vlan 100
