Chapter 2 System Messages and Recovery Procedures STP Messages Send document comments to [email protected] Error Message STP-2-BLOCK_DETECTED_PVST_PEER: Blocking port [chars] [PVST peer detected]. Explanation The listed interface received SSTP BPDU indicating that the peer is running PVST and will be held in spanning tree blocking state until the interface stops receiving SSTP BPDUs. Recommended Action Either enable PVST simulation configuration for the interface or make sure the port peer is not PVST switch. Error Message STP-2-BLOCK_PVID_LOCAL: Blocking [chars] on [chars]. Inconsistent local vlan. Explanation The spanning tree port associateddd with the listed spanning tree instance and interface will be held in spanning tree blocking state until the Port VLAN ID (PVID) inconsistency is resolved. The listed spanning tree instance is that of the native VLAN ID of the listed interface. Recommended Action Verify that the configuration of the native VLAN ID is consistent on the interfaces on each end of the 802.1Q trunk connection. Once corrected, spanning tree will automatically unblock the interfaces as appropriate. Error Message STP-2-BLOCK_PVID_PEER: Blocking [chars] on [chars]. Inconsistent peer vlan. Explanation The spanning tree port associateddd with the listed spanning tree instance and interface will be held in spanning tree blocking state until the port VLAN Id (PVID) inconsistency is resolved. The listed spanning tree instance is that of the native VLAN ID of interface on the peer switch to which the listed interface is connected. Recommended Action Verify that the configuration of the native VLAN ID is consistent on the interfaces on each end of the 802.1Q trunk connection.

As a result, the interface was moved to the spanning tree Blocking state. Recommended Action No user action is required. Error Message STP-2-BRIDGE_ASSURANCE_UNBLOCK: Bridge Assurance unblocking port [chars] [chars]. Explanation The interface listed in the message has been restoredddd to normal spanning tree state after receiving BPDUs from the neighboring L2 switch/bridge.
