I'm installing a new switch into a shared office, and I've started playing with 802.x or is it 802.1x :)
Anyway, the idea is that only authorised computers should be able to connect to the network as it is a shared environment, and I wanted to stop any attempt of simply plugging a laptop in and getting an IP address via DHCP, it is a wired ethernet network. On top of that I have the normal usernames and passwords deal for network resources - but if it is a computer that I am not aware of in the first place, I dont even want it to be able to broadcast a DHCP request on the network.
I figured that I would be able to do this easily with MAC address filtering, and I was informed that the Cisco ESW 520 switch could do this. As we have bar code scanners, the process of getting the MAC address in the first place is trivial.
I figured that all I needed to do was to enter a list of MAC addresses, and the job's done.
However, I am overwhelmed by the configuration on the Cisco ESW 520, and it appears I've bitten off more than I can chew.
It seems that I need to create ACL's and then associate the ACL's to ports on the switch - I'm completely lost and have no idea how to proceed with what should be a trivial thing.
