  • Limit Layer 2 Traffic between two interfaces

    I have a Cisco 6509. I have a dot1q VLan and a physical interface FA3/1. I want to only route between these two interfaces. What is the most effect way to configure this?

    So you have a dot1q trunk coming from another switch? Is the fa3/1 interface a switchport or a routed port? Need some more info.

      I have a QMOE circuit from Centurylink on the VLan. The FE3/1 is currently configured as a switchport which is a crossconnect from another customers router. We really just want to bridge the two ports together and neither would have access to any other port on the switch. I have reviewed the ACL option, but that would be a lot of entries to cover everything. Would that really be efficient to do?

        Can you post a diagram of what this would look like?
