Configuring the MAC address table 4

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 “Layer 2 Ethernet overview” on page 3.

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
