Hi Stephen,
That’s the exactly scenario that we are facing. We are going to change a BigIron 8000 for a S4 Chassis. Actually, the passing communication is doing well if and only if the spanning tree is disabled in the Foundry’s uplinks port to the S4 Chassis, but still enable globally on both. In your case that you disabled the spanning tree globally in the S4 Chassis, what are you doing for stop loops in the S4 Chassis? I mean, because if the spanning tree is disabled globally I think that no matter if the spanning tree portadmin status is enable on ports, it will not work… or my thinking is wrong?

We still have all the foundry edge switches running the IDFs on campus. In order for this to work for us with redundant links to the foundry edge switches, we disabled STP globally in the S4 and in each foundry switch and configured LACP for the uplink trunks. STP and LACP don't mix as STP is trying to bring down the redundant link and LACP is trying to use it for load balancing.

I’m trying to connect the S4 Chassis (CORE) to some Foundry EdgeIron Switches (DISTRIBUTION and EDGE) and the only way that I’m able to pass communication between links is disabling the spanning tree on the Foundry uplink port to the S4 Chassis. If I have enable the spanning tree globally and on the uplinks port in both the communication hangover. The firmware operation code of the EdgeIron 4802cf is 2.2.4.29. The S4 Chassis has the latest firmware installed 7.11.01.0026 released on 01-Nov-2010. If have LACP configured in both the only way that I’m able to pass communication between both is disabling the spanning tree on the S4 Chassis uplink port, because the Foundry’s one when configured the LACP it disable automatically the spanning tree on the ports forming the LACP and in the LACP itself.
