Thanks Markus, okay so that got it out of dormant and up, but it still won't let the switch come up if I unplug it from the second core. One thing I should probably mention on this is that there are two lags between the cores. A 20 gig lag with two 10 gig ports in it and a 2 gig lag with two copper gig links. If I unplug the 2 gig lag then the core goes down. If I leave that one plugged up and bring down the 20 gig lag then nothing happens and the link stays up. I've been thinking ever sense I inherited this installation that something was wrong there and I'm not sure if this is related to my other issue or not, but it seems feasible.

In most cases this is 802.1ad LACP protocol. LACP is enabled by default and if you connect two ports between two devices, then a logical port (lag.x.x) is created via LACP protocol. If this happens, you need to tag (vlan egress list) all required vlans also to the formed lag.x.x port (check via show lacp command), not just the physical port. If you don't want to use LACP and STP instead for redundant links, you can disable LACP globally (set lacp disable) or per port (set port lacp port ge.x.x disable) or for all ports (set port lacp port *.*.* disable). This should solve your problem. Cheers, Markus Sent via iPhone.

I have a dual core configuration with N7 chassis. This was set up so that the edge switches each had a fiber plugged into each core. I'm working on dropping out this second core and as a result I'm dropping the second connection. For the most part this has went without incident, but I have a couple of these where the port they are plugged into on the core I'm keeping is set to dormant and spantree is blocking. So essentially when I disconnect the edge for the second core the switch goes down. I've tried everything I can think of to get the ports to come off dormant and forward traffic but it does not matter. Even plugging into another port on these two vlans( there are only two that are affected) will set that port as blocking. I've looked at the edge sw2ithces and do not see anything that should be causing this. I've also looked to make sure I did not have a loop on the edge switches. I've got a call into GTAC right now, but I was just wonder if any one else had ever seen anything like this and could get me a clue or tell me how to force the ports to start forwarding traffic.
