Hello all,
I have a Catalyst 6509-E with SUP2T and a WS-68xx series SFP line card. On this line card I will have 5 trunk connections going to ME3400 4 port access switches. There is one tagged VLAN allowed on all trunk ports and it is the same across them all. I need to have one trunk connection be allowed to switch to all ports within this VLAN and the remaining 3 ports be denied to switch between eachother. The remaining three ports would only be able to switch to the primary trunk port.
For informational purposes I want to point out that the downstream ME3400 access switches are performing QinQ on each connection so that when the traffic reaches the 6509 it will be double tagged.
Traditionally I have been able to do this on 12 port ME3400s using the built in UNI/NNI structure and on ME3800/3600 switches using EVCs and the "split-horizon" keyword on the bridge domain. However, the 6500 doesn't seem to support either one of these commands.
Does anyone have any ideas on how to accomplish this?
