Configuring the MAC port security feature
35
PowerConnect(config)#interface ethernet 7/11
PowerConnect(config-if-e1000-7/11)#port security
PowerConnect(config-port-security-e1000-7/11)#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).
Specifying secure MAC addresses
You can configure secure MAC addresses on tagged and untagged interfaces.
On an untagged interface
To specify a secure MAC address on an untagged interface, enter commands such as the following.
PowerConnect(config)#interface ethernet 7/11
PowerConnect(config-if-e1000-7/11)#port security
PowerConnect(config-port-security-e1000-7/11)#secure-mac-address 0050.DA18.747C
Syntax: [no] secure-mac-address <mac-address>
On a tagged interface
When specifying a secure MAC address on a tagged interface, you must also specify the VLAN ID.
To do so, enter commands such as the following.
PowerConnect(config)#interface ethernet 7/11
PowerConnect(config-if-e1000-7/11)#port security
PowerConnect(config-port-security-e1000-7/11)#secure-mac-address 0050.DA18.747C 2
Syntax: [no] secure-mac-address <mac-address> <vlan-ID>
NOTE
If MAC port security is enabled on a port and you change the VLAN membership of the port, make
sure that you also change the VLAN ID specified in the secure-mac-address configuration statement
for the port.
When a secure MAC address is applied to a tagged port, the VLAN ID is generated for both tagged
and untagged ports. When you display the configuration, you will see an entry for the secure MAC
addresses. For example, you might see an entry similar to the following line.
secure-mac-address 0000.1111.2222 10
This line means that MAC address 0000.1111.2222 on VLAN 10 is a secure MAC address.
Autosaving secure MAC addresses to the
startup-config file
Learned MAC addresses can automatically be saved to the startup-config file at specified intervals.
For example, to automatically save learned secure MAC addresses every 20 minutes, enter the
following commands.
PowerConnect(config)#port security
PowerConnect(config-port-security)#autosave 20
