MAC port security configuration
Setting the maximum number of secure 
MAC addresses for an interface
When MAC port security is enabled, an interface can store one secure MAC address. You can 
increase the number of MAC addresses that can be stored to a maximum of 64, plus the total 
number of global resources available.
For example, to configure interface 1/1/7 to have a maximum of 10 secure MAC addresses, enter 
the following commands.
Brocade(config)# interface ethernet 1/1/7
Brocade(config-if-e10000-1/1/7)# port security
Brocade(config-port-security-e10000-1/1/7)# maximum 10 
Syntax: maximum number-of-addresses
The number-of-addresses parameter can be set to a number from 0 through 64 plus (the total 
number of global resources available). The total number of global resources is 2048 or 4096, 
depending on flash memory size. Setting the parameter to 0 prevents any addresses from being 
learned. The default is 1.
Setting the port security age timer
By default, learned MAC addresses stay secure indefinitely. You can optionally configure the device 
to age out secure MAC addresses after a specified amount of time.
To set the port security age timer to 10 minutes on all interfaces, enter the following commands.
Brocade(config)# port security
Brocade(config-port-security)# age 10
To set the port security age timer to 10 minutes on a specific interface, enter the following 
commands.
Brocade(config)# interface ethernet 1/1/7
Brocade(config-if-e10000-1/1/7)# port security
Brocade(config-port-security-e10000-1/1/7)# age 10
Syntax: [no] age minutes
The minutes variable specifies a range from 0 through 1440 minutes.The default is 0 (never age 
out secure MAC addresses).
NOTE
Even though you can set age time to specific ports independent of the device-level setting, the actual 
age timer will take the greater of the two values. Thus, if you set the age timer to 3 minutes for the 
port, and 10 minutes for the device, the port MAC aging happens in 10 minutes (the device-level 
setting), which is greater than the port setting that you have configured.
