There is a whole laundry list of items that must be configured identically on both switches. To see the status of these items, add the global keyword to the show vpc consistency-paramen command. If any of the type-1 items are mismatched, your vPCs won't work. I've seen problems when working with vPCs in which the show vpc command reported a configuration mismatch where none existed. If this happens, remove the port channel interface and the channel group commands from the physical interfaces. When you replace them, the vPC will likely work. I've seen this behavior on 4.x and 5.x code on the NX-7K-2-Annie(config)# sho vpc consistency-parameters global Legend: Type 1 : vPC will be suspended in case of mismatch Local Value Peer Value STP Mode Rapid-PVST Rapid-PVST STP Disabled STP MST Region Name STP MST Region Revision STP MST Region Instance to VLAN Mapping STP Loopguard Disabled Disabled STP Bridge Assurance Enabled Enabled STP Port Type, Edge Normal, Disabled, Normal, Disabled, BPDUFilter, Edge BPDUGuard Disabled Disabled STP MST Simulate PVST Enabled Enable
