Deny packets from routers

[bondandrey]

Hello!

Some users bring their own wifi routers to work and connet them to our network instead of computer(clone ip & mac adresses).

Is it possible to determine that pakets pass through such router and deny them using ASA 5515 with PRSM?

Thanks!

You can/should filter that at the switch level. Do you have Cisco switches?

Thanks for your answer Collin!

Now we don't have Cisco switches.

Please, can you tell me how to do this. Give me link to manual or something.
