We have a remote connection from our core 5k's to a 4506 at the remote building. Currently one connection is up and running fine in normal trunking mode. However, when we bring up the secondary connection we get a loop that brings down the connection. The exact error message from logs is:
Nexus 5548UP - %FWM-2-STM_LOOP_DETECT
I have read that if there is NIC bonding occurring at the remote site on some servers that this could be the issue. I understand that. However, my question is this:
Can I just create a VPC by bundling the the 2 connections from my two 5k's to the 4506 and eliminate spanning tree altogether? It seems that this would be a viable solution. VPC does, after all, eliminate spanning tree.
Assistance is greatly appreciated,
