ITN Practice PT Skills Assessment (PTSA) Answers The port security that was enabled on the port only allowed the device, whose MAC was learned first, access to the port while preventing all other devices access. Why is PC2 able to ping PC1, but the Rouge Laptop is not? Disconnect Rouge Laptop and reconnect PC2.There should be a violation count of at least four, one for each ping request. Display the port security violations for the port to which Rogue Laptop is connected.Verify that Rogue Laptop is unable to ping PC1. Disconnect PC2 and connect Rogue Laptop to F0/2, which is the port to which PC2 was originally connected.

After verification, shut down the port connected to Rogue Laptop.

Enable the port and verify that Rogue Laptop can ping PC1 and PC2.

Attach Rogue Laptop to any unused switch port and notice that the link lights are red.

Use port-security show commands to display configuration information.

Verify that port security is enabled and the MAC addresses of PC1 and PC2 were added to the running configuration.

S1(config-if- range)# shutdown Step 2: Verify Port Security S1(config-if- range)# interface range f0/3 – 24, g0/1 – 2 Use the range keyword to apply this configuration to all the ports simultaneously.

Disable all the remaining unused ports.

S1(config-if- range)# switchport port-security violation restrict

Set the violation mode so that the Fast Ethernet ports 0/1 and 0/2 are not disabled when a violation occurs, but a notification of the security violation is generated and packets from the unknown source are dropped.S1(config-if- range)# switchport port-security mac-address sticky

Secure the ports so that the MAC address of a device is dynamically learned and added to the running configuration.S1(config-if- range)# switchport port-security maximum 1 Set the maximum so that only one device can access the Fast Ethernet ports 0/1 and 0/2.S1(config-if- range)# switchport port-security Access the command line for S1 and enable port security on Fast Ethernet ports 0/1 and 0/2.Port security allows you to restrict a port ’ s ingress traffic by limiting the MAC addresses that are allowed to send traffic into the port. In this activity, you will configure and verify port security on a switch.
