SPANTREE Messages
This section contains the spanning-tree messages.
Error Message SPANTREE-2-BLOCK_BPDUGUARD: Received BPDU on port [chars] with BPDU
Guard enabled. Disabling port.
Explanation A bridge protocol data unit (BPDU) was received on an interface that has the spanning
tree BPDU guard feature enabled. As a result, the interface was administratively shut down. [chars]
is the interface name.
Recommended Action Either remove the device sending BPDUs, or disable the BPDU guard feature.
The BPDU guard feature can be locally configured on the interface or globally configured on all
ports that have PortFast enabled. To disable BPDU guard on an interface, use the no spanning-tree
bpduguard enable interface configuration command. To disable BPDU guard globally, use the no
spanning-tree portfast bpduguard default global configuration command. After you have
removed the device or disabled BPDU guard, re-enable the interface by entering the no shutdown
interface configuration command.
Error Message SPANTREE-2-BLOCK_BPDUGUARD_VP: Received BPDU on port [chars], vlan
[dec] with BPDU Guard enabled. Disabling vlan.
Explanation A bridge protocol data unit (BPDU) was received on the interface and VLAN specified
in the error message. The spanning tree BPDU guard feature was enabled and configured to shut
down the VLAN. As a result, the VLAN was placed in the error-disabled state. [chars] is the
interface, and [dec] is the vlan.
Recommended Action Either remove the device sending BPDUs, or disable the BPDU guard feature.
The BPDU guard feature can be locally configured on the interface or globally configured on all
ports that have Port Fast enabled. Re-enable the interface and vlan by entering the clear errdisable
privileged EXEC command.
Error Message SPANTREE-2-BLOCK_PVID_LOCAL: Blocking [chars] on [chars]. Inconsistent
local vlan.
Explanation The spanning-tree port associated with the listed spanning-tree instance and interface
will be held in the 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. The
first [chars] is the interface, and the second [chars] is the spanning-tree instance.
Recommended Action Verify that the configuration of the native VLAN ID is consistent on the
interfaces on each end of the IEEE 802.1Q trunk connection. When corrected, spanning tree
automatically unblocks the interfaces, as appropriate.
