Task 8: Verify the Results<br />

Verify the MAC address table entries.<br />

ALSwitch#show mac-address-table<br />

How many static addresses exist? 5<br />

ALSwitch#show mac-address-table<br />

Task 9: List Port Security Options<br />

Step 1. Determine options for setting port security on interface Fast Ethernet 0/4. Enter switchport<br />

port security ? from the interface configuration prompt for Fast Ethernet port 0/4.<br />

ALSwitch(config)#interface fastethernet 0/4<br />

ALSwitch(config-if)#switchport port-security ?<br />

aging Port-security aging comm<strong>and</strong>s<br />

mac-address Secure mac address<br />

maximum Max secure addresses<br />

violation Security violation mode<br />

<br />

1900:<br />

ALSwitch(config)#interface ethernet 0/4<br />

ALSwitch(config-if)#port secure ?<br />

max-mac-count Maximum number of addresses allowed on the port<br />

<br />

Step 2. Allow the switch port fastethernet 0/4 to accept only one device by using the following comm<strong>and</strong>s:<br />

ALSwitch(config-if)#switchport mode access<br />

ALSwitch(config-if)#switchport port-security<br />

ALSwitch(config-if)#switchport port-security mac-address sticky<br />

1900:<br />

ALSwitch(config-if)#port secure
