The link was quite useful. But how can we allow certain mac address only to pass thru. What is happening in my LAN is that users are swapping IP addresses in order to browse internet. What I want is only allow mac address of particual PC/laptop only to pass thru. Thanks in advance.
if your users are able to swap IP addresses by themselves, I assume you are not using DHCP ? Just be aware that blocking/allowing MAC addresses would not really have an effect on the access the corresponding IP address has. Let's say your user's NIC has MAC address 0012.3456.7890, and you allow that MAC address (to access the Internet), it would not really matter what IP address is assigned to the NIC; any IP addresses configured on the NIC would be able to pass through. So your users could still swap IP addresses and access the Internet, as long as you allow the MAC address.
Also, MAC address access lists only affect non-IP traffic, which means that they won't have any effect when trying to filter IP hosts.
Wouldn't a standard or extended access list be suffucient, where you specify which addresses you want to allow to access the Internet ?
In that case you need to have a Proxy-server which can validate a user, establish a connection to internet.In some of the servers, you can bind a user to that MAC etc.This can be achieved using following combinations :
(1)Use a Third party proxy server like Mikrotik etc. to validate users.
(2)Use Cisco ASA/PIX or something like that to validate users.
(3)Create dial-in users on your non-core router (say PPPoE etc).
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
