Changing the MAC age time
2
The ability of the CAM to store depends on the following:
• The number of source MAC address being learned by the CAM.
• The number of destination MAC addresses being forwarded by the CAM
• The distribution of the MAC address entries across ports. For example, it one port is learning all
the source MAC addresses, the available of the CAM for that port will be depleted.
Example
In the following example, a static MAC address of 0000.0063.67FF with a priority of 7 is assigned
to port 2 of module 1 in VLAN 200.
Brocade(config)# vlan 200
Brocade(config)# static-mac-address 0000.0063.67FF e 1/2 priority 7
Syntax: [no] static-mac-address mac-addr ethernet portnum [priority number]
The mac-addr variable specifies the MAC address that you assigning.
The portnum variable specifies the Ethernet port that the MAC address is being assigned to.
Using the priority option, you can assign a value to the number variable of 0 – 7.
Changing the MAC age time
The MAC age time sets the aging period for ports on the device, defining how long (how many
seconds) a port address remains active in the address table.
To change the aging period for MAC addresses from the default of 300 seconds to 600 seconds.
Brocade(config)# mac-age-time 600
Syntax: [no] mac-age-time age-time
The age-time can be 0 or a number from 60 – 65535. The zero results in no address aging. The
default is 300 (seconds).
Configuring static ARP entries
When you create a static ARP entry, the Brocade device automatically creates a static MAC entry.
NOTE
To delete the static MAC entry, you must delete the static ARP entry first.
