Then run following commands on switch and test connectivity from the authorized PC ( PC1): Switch(config)#interface fa0/1 Unplug the cable from unauthorized PC( new PC) and plug it back to authorized PC( PC1) One of the options on the table is to manually restart the shutdown interface( fa0/1 in our case here).

How to Reset an interface that has been shut down due to Violation of Port Security: Verify from above that port status is now Secure-shutdown upon violation of port security.įurther, a ping from the New PC to PC2 will definitely fail because the switch cannot forward a frame via an interface that is shut down. You can verify this further by using the command we used before: show port-security interface fa0/1

So attaching the new PC to fa0/1 violates the port security rules that we set and as a result, the interface shuts down.

This is because the switch had already associated fa0/1 with the MAC address of PC1 and the maximum number of MAC addresses that we defined for this port is 1. Notice that fa0/1 shuts down upon connecting the new PC, as indicated by the red LED. Now connect a different PC to fa0/1 in place of PC1. Ping should be successful here since switch port security is not violated. You may also use the command: show port-security address Verify that the switch has learnt the MAC address of PC1. To verify if the switch has learnt the MAC address of PC1, you can use the command: We’ll verify port security configurations on interfaces fa0/1 and fa0/2 The interface range command can save you tons of work in doing individual configurations if you were configuring port security for many switch interfaces, say, 24 ports on a switch.Ĥ. Here, we define a range of interfaces on which we want to configure port security, then proceed to configure port-security for all the interfaces specified at a go instead of one interface at a time. That’s all for port-security configuration on fa0/2Ī shorthand method for configuration :The port security configurations for both fa0/1 and fa0/2 could be done more faster with the help of interface range command as shown below: Switch(config-if-range)#interface range fa0/1-2 Switch(config-if)#switchport port-security violation shutdown In a similar way to switch interface fa0/1, configure switch port security for fa0/2 connected to PC2 : Switch(config)#interface fa0/2 We’re are done with port security configuration for fa0/1 Switch(config-if)#switchport port-security maximum 1 Let’s add the above 2 commands to our configuration: Switch(config-if)#switchport port-security violation shutdown

The sticky keyword instructs the switch to dynamically learn the MAC address of the currently connected host. Switch(config-if)#switchport port-security mac-address sticky Switch(config-if)#switchport port-security Here are the commands: Switch(config)#int fa0/1

If an unauthorized device is connected to the same port, you can define the action that the switch will take, such as discarding the traffic, sending an alert, or shutting down the port. This will enable you to restrict access to a given switch interface so that only the authorized devices can use it. Switch port Security is a network security feature that associates specific MAC addresses of devices(such as PCs) with specific interfaces on a switch. Hello and welcome! In this tutorial, we’ll have an overview of switch port security then configure it in Packet Tracer.
