Re : To ban a MAC address on a network.

[sanjay.nadarajah]

Hi,

I have an environment that has 6500 series as the core/distrubution switch and 3750 stack as the access switches across five floors.

My question is can I ban a MAC address from the whole environment ? If yes, how can this be done.

Thank you.

cheers,

Hi,

     Let's say you don't allow "abcd.efgh.ijkl" in your network. You have used VLAN-10,VLAN-20 and VLAN-30. I'd do the following command on each switch.

C3750-1, C3750-2 ....  and C6500

!

mac address-table static abcd.efgh.ijkl vlan 10 drop

mac address-table static abcd.efgh.ijkl vlan 20 drop

mac address-table static abcd.efgh.ijkl vlan 30 drop

!

   It's a good idea to use copy/paste to get this job done.

HTH,
