Equipment<br />

The topology shown in Figure 6-15 is using a 2950 Catalyst series switch. You also need two different PCs<br />

to test the port security.<br />

Note: Comm<strong>and</strong> output for this lab is based on a 2950 series switch running Cisco IOS version 12.1(13)EA1. The<br />

comm<strong>and</strong>s you need to use <strong>and</strong> the output may differ. If necessary, consult with your instructor for the correct comm<strong>and</strong>s.<br />

Alternatively, you can research the comm<strong>and</strong>s for your particular switch platform <strong>and</strong> IOS at Cisco.com. This<br />

would be an excellent way to enhance your Cisco device configuration skills <strong>and</strong> to simulate a “real-world” situation,<br />

namely, researching the comm<strong>and</strong> set for a particular device that is a part of your production network.<br />

NetLab Compatibility Notes<br />

Much of this lab can be completed on a NetLab basic switch pod. However, to test port security, your<br />

NetLab setup must support PCs.<br />

Task 1: Cable the Topology <strong>and</strong> Clear the Configuration<br />

Step 1. Choose a 2950 switch <strong>and</strong> attach a workstation to FastEthernet 0/4.<br />

Step 2. Make sure the switch has an empty startup configuration <strong>and</strong> that the VLAN database has been<br />

deleted. Then, reload the switch. What comm<strong>and</strong>s must be used to carry out this instruction?<br />

How do you verify that the VLAN database has been deleted?<br />

Switch#erase startup-config<br />

Switch#delete flash:vlan.dat<br />

Switch#reload<br />

Use the comm<strong>and</strong> show flash to verify that the vlan.dat file has been deleted.<br />

Task 2: Configure the Switch<br />

Step 1. Configure the switch with the following basic requirements:<br />

■ Hostname<br />

■ Enable password<br />

■ Banner MOTD<br />

■ Line configurations<br />

■ Other instructor-required global configurations<br />

Step 2. Check your configurations. What comm<strong>and</strong> did you use?<br />

show running-config<br />

Step 3. Although there is not a router shown in Figure 6-15, one would eventually be attached.<br />

Configure the management interface, activate it, <strong>and</strong> configure 192.168.1.1 as the default gateway.<br />

What comm<strong>and</strong>s did you use?<br />

ALSW(config)#interface vlan1<br />

ALSW(config-if)#ip address 192.168.1.2 255.255.255.0<br />

ALSW(config-if)#no shutdown<br />

ALSW(config)#ip default-gateway 192.168.1.1<br />
