a. From the router R1 CLI, use the show interface command and record the MAC address of the
interface. R1 show interface fa01 FastEthernet01 is up, line protocol is up Hardware is Gt96k FE, address is 001b.5325.256f bia 001b.5325.256f Internet address is 192.168.1.124 MTU 1500 bytes, BW 100000 Kbitsec, DLY 100 usec, reliability 255255, txload 1255, rxload 1255 Encapsulation ARPA, loopback not set Keepalive set 10 sec Full-duplex, 100Mbs, 100BaseTXFX b. What is the MAC address of the R1 Fa01 interface? In the example above, it is 001b.5325.256f. Step 2: Configure basic port security. This procedure should be performed on all access ports that are in use. Switch S1 port Fa05 is shown here as an example. Note: A switch port must be configured as an access port to enable port security. a. From the switch S1 CLI, enter interface configuration mode for the port that connects to the router Fast Ethernet 05. S1config interface FastEthernet 05 b. Shut down the switch port. S1config-if shutdown c. Enable port security on the port. S1config-if switchport port-security Note: Entering just the switchport port-security command sets the maximum MAC addresses to 1 and the violation action to shutdown. The switchport port-security maximum and switchport port-security violation commands can be used to change the default behavior. d. Configure a static entry for the MAC address of R1 Fa01 interface recorded in Step 1. S1config-if switchport port-security mac-address xxxx.xxxx.xxxx xxxx.xxxx.xxxx is the actual MAC address of the router Fast Ethernet 01 interface. Note: Optionally, you can use the switchport port-security mac-address sticky command to add all the secure MAC addresses that are dynamically learned on a port up to the maximum set to the switch running configuration.

S1config-if no shutdown Step 3: Verify port security on S1 Fa05.a. On S1, issue the show port-security command to verify that port security has been configured
