How does one resolve this inconsistentcy

Re: VTP BLK meaning

Error Message: SPANTREE-2-LOOPGUARDBLOCK: No BPDUs were received on port [chars] in [chars] [dec]. Moved to loop-inconsistent state

Explanation: This message indicates that due to a unidirectional link failure, or failure of a bridge, BPDUs are not being received on the port. Loopguard has blocked the port to prevent loops.

Check the bridge connected to this port and test the link for any unidirectional failures. Sometimes excessive delay between BPDUs can trigger this event. If this is the case, no action is required because the port state is restored with the arrival of the next BPDU.
