MAC-Address Filter on 3550-12G Switch

Hi,

Is there a way to create a layer-2 filter in 3550 to Deny Traffic going from e.g. gig0/7 to gig0/6 ? (Other than Implementing VLANs)

Re: MAC-Address Filter on 3550-12G Switch

Hi,

Thank you for your help.

Though i have a slightly different situation. On my 355012g switch, i want

Port gig0/1 - gig/11 To talk to each other without a layer Three Device. All of these ports are Trunk Links.

Port gig 0/12. For this Port i don't want the traffic to go to some specific Ports\Trunks (e.g. gig0/1 etc). This port is a member of a different VLAN and is NOT a trunk.

I guess VLAN Pruning would help me in this case?

It would appear to me that you would just put g0/12 in a vlan not included in the trunks for int g0/1-11. This would keep the traffic from leaving port g0/12.

Is this what you were looking for?

Yes. Thats what i was planning to do but wasn't sure if this is a good solution.

Thank you.
