I have a 2950 switch and I want to block or drop all ip traffic on port 368. All of the ports are all on a single VLAN (eg VLAN 40). What is most efficient way to do this? VACL? If you could provide an example of the appropriate commands that would be most helpful.
If the port 368 traffic is trying to leave the vlan, then a VACL would suffice.
If you want to prevent the traffic from going to another host on the same vlan, a vlan map would be the answer. However, I don't think (or know) that the 2950 supports vlan maps. The 3550 does, and here is a link:
What you can do is just configure ACL and when it comes to applying on an interfaces you can use "interface range" command to configure any changes on as many interfaces as you want which you may have selected in interface range command.
