Is the new backup link just a dark fiber connection between the two boxes? From the error message it looks like the frames are being seriously corrupted at some point and that is causing the problems.
The SPANTREE-SP-2-RECV_PVID_ERR error message indicates that the PVST+ BPDU for vlan 53 was received on vlan 55. Looking at your configuration I don't see how this is possible. I have seen some strange behavior with faulty Supervisors, but nothing like this. > Hi, > > Tonight we tried to bring up a second link between two 6500 (backup > link).
