That's exactly the command set I used. Didnt show up in the running config.

Thanks for the feedback. Perhaps if you provide us a copy of your running config we can see something missing... i.e. port shutdown or no vlan in vtp domain database.......

Shouldn't have to do that really. That's kind of the purpose of the portchannel in the first place. I will have about 16 different port channels on each 6513. Largest portchannel will be 4 ports. I'd prefer to just configure the portchannel with the VLANs as opposed to all the physical ports.

Interesting thought. Will give it a shot. But right now it says I have NONE allowed. Maybe a little reverse psychology will do the switch good!

Glen you were definitely on the right track. I brought up the other side of the portchannel so I could troubleshoot.

What it ended up being is that on CoreA I had VLANs 1-4094 allowed and on CoreB I had only the VLANs I wanted to allow in the config.

I remembered that some point in the early troubleshooting of this issue that I put the switchport trunk allowed VLAN add all command. Unfortunately for Cisco users, this actual command does not show up in the running config.

I ended up doing a switchport trunk allowed vlan none command then issued the switchport trunk allowed vlan 2,100,110 and now only those correct VLANs are on the trunk.

Thanks for everyone's help. Now I am off to configure the HA for the FWSM on the two Chassis. I am sure you will hear from me again soon.

Five stars to Glen! Thanks.
