Try to test your switch port security configuration with ping command and testing with the rogue laptop on the lab. a. From PC1, ping PC2. b. Verify port security is enabled and the MAC addresses of PC1 and PC2 were added to the running configuration with "show run" command. c. Attach Rogue Laptop to any unused switch port and notice that the link lights are red.

Try to test your switch port security configuration with ping command and testing with the rogue laptop on the lab. a. From PC1, ping PC2. b. Verify port security is enabled and the MAC addresses of PC1 and PC2 were added to the running configuration with "show run" command. c. Attach Rogue Laptop to any unused switch port and notice that the link lights are red.This will disable the secure port, if any other device other than the one with the above MAC-Address connects to the switch port. If there is a switch or a hub (say 12 port or a 24 port) that connects to the switchport which you want to secure then you can set the maximum number of MAC-Addresses that connects to the port and/or set the MAC ... Yes, I have done this before. You just need to configure a trunk port on the Cisco switch that connects to pfSense. On pfSense you have to tag the VLANs on the interface that leads to your cisco switch. The access ports on the cisco switch that leads to your client need to have the VLANs untagged. On pfSense you can setup DHCP for each VLAN. VLAN natif: Le vlan appelé "natif" est le vlan par défaut du switch (en général le vlan 1). Sans configuration, tous les ports du switch sont placés dans ce VLAN. Ce vlan n'est pas marqué même si il passe sur une liaison trunk. Configuration type d'un switch: La liaison entre les switchs est en mode trunk. In this lesson I will demonstrate how to configure a trunk between Cisco Catalyst switches. Let me show you the topology that we’ll use: Above you see a topology with a computer connected to each switch. We’ll put the computers in the same VLAN and create a trunk between the two switches.
