Is there anyway to block a given MAC from trying to authenticate to the PPPoE server? I have a few usernames that keep trying to connect and are filling up my log files.

You can add caller-id for ‘ppp secret’, set MAC-address to caller-id, then only user with that MAC-address will be able to use particular PPPoE login/password.
I want to block that MAC completely simply because its repeated attempts to connect clutter up my log file.

For the wireless you may disallow connection for this MAC-address by access-list.
For the Ethernet you need to find switch, where client is connected and unplug that user from the switch.
We’re using an automated script that check all login attempts and blocks specific MACs in bridge filters if user is trying to connect more than 3 times in 60 seconds, block lasts for sometime and then it’s auto-removed.
This also helps to lower the load on an auth server when there’s a lot of disconnected clients with negative balance.
Can you please share that script with us . i have started to write that script but it is a little time consume and a guide will be very helpful .
thanks
This is a great idea. It´s possible to share it with us?
