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. After the conflict has been resolved, re-enable the interface by entering the no shutdown interface configuration command.

Error Message    SPANTREE-2-BLOCK-PVID-LOCAL: Blocking [chars] on [chars] Inconsistent 
local vlan.

Explanation    This message means that the spanning-tree port associated with the listed spanning-tree instance and interface will be held in the spanning-tree blocking state until the per-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 802.1Q trunk connection. When corrected, spanning tree automatically unblocks the interfaces, as appropriate.

Error Message    SPANTREE-2-BLOCK-PVID-PEER: Blocking on [chars] [chars]. Inconsistent 
peer vlan.

Explanation    This message means that 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 interface on the peer switch to which the listed interface is connected. 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 802.1Q trunk connection. When it is corrected, spanning tree automatically unblocks the interfaces, as appropriate.

Error Message    SPANTREE-2-CHNL_MISCFG: Detected loop due to etherchannel 
misconfiguration of [chars] [chars] 

Explanation    This message means that a loop that caused the misconfiguration of a channel group has been detected. An example of such a misconfiguration would be when the ports on one side of the EtherChannel either are not configured to be in the channel or failed to bundle for some reason. The other side has successfully bundled the ports into the EtherChannel.

Recommended Action    Determine which local ports are involved by using the show interfaces status err-disabled privileged EXEC command, and then verify EtherChannel configuration on the remote device by using the show etherchannel summary user EXEC command on the remote device. When the configuration is corrected, enter shutdown and no shutdown interface configuration commands on the associated port-channel interface.

Error Message    SPANTREE-2-LOOPGUARD_BLOCK: Loop guard blocking port [chars] on 
[chars]. 

Explanation    This message means that the spanning-tree message age timer has expired because no bridge protocol data units (BPDUs) were received from the designated bridge. Because this condition could be caused by a unidirectional-link failure, the interface is put into the blocking state and marked as loop-guard-inconsistent to prevent possible loops from being created. The first [chars] is the name of this port, and the second [chars] is the spanning-tree mode displayed in the show spanning-tree privileged EXEC command.

Recommended Action    Enter the show spanning-tree inconsistentports privileged EXEC command to review the list of interfaces with loop-guard inconsistencies. Determine why devices connected to the listed ports are not sending BPDUs. One reason might be that they are not running the Spanning Tree Protocol (STP). If so, you should disable loop guard on the inconsistent interfaces by using the spanning-tree guard none interface configuration command or by starting STP on the remote side of the links.

Error Message    SPANTREE-2-LOOPGUARD_CONFIG_CHANGE: Loop guard [chars] on port [chars] 
on [chars]. 

Explanation    This message means that the spanning-tree loop-guard configuration for the listed interface has been changed. If enabled, the interface is placed into the blocking state. It is marked as loop-guard-inconsistent when the message-age timer expires because no BPDUs were received from the designated bridge. This feature is mainly used to detect unidirectional links. The first [chars] is the loop-guard state (enable or disable), the second [chars] is the interface name, and the third [chars] is the spanning-tree instance.

Recommended Action    Verify that this is the desired configuration for the listed interface. Correct it if this is not the desired configuration; otherwise, no further action is required.

Error Message    SPANTREE-2-LOOPGUARD_UNBLOCK: Loop guard unblocking port [chars] on 
[chars]. 

Explanation    This message means that the listed interface has received a BPDU, and, therefore, if the inconsistency was caused by a unidirectional link failure, the problem no longer exists. The loop-guard-inconsistency is cleared for the interface, which is taken out of the blocking state, if appropriate. The first [chars] is the name of this port, and the second [chars] is the spanning-tree mode displayed in the show spanning-tree privileged EXEC command.

Recommended Action    No action is required.

Error Message    SPANTREE-2-PVSTSIM_FAIL: Superior PVST BPDU received on VLAN [dec] 
port [chars], claiming root [dec]:[enet]. Invoking root guard to block the port.

Explanation    This message means that when a per-VLAN spanning-tree plus (PVST+) switch is connected to a Multiple Spanning Tree Protocol (MSTP) switch, the internal spanning-tree (IST) root (MST00) becomes the root for all PVST+ spanning trees. A loop might be created if any of the PVST+ spanning trees have a better root than the IST. To prevent the loop, the port on the MSTP switch that receives the superior message from the PVST+ side is blocked by root guard. The first [dec] is the VLAN number, [chars] is the port name, and [dec]:[enet] is the priority and MAC address.

Recommended Action    When STP is converging after a new switch or switch port is added to the topology, this condition might happen transiently, and the port automatically unblocks in these cases. If the port remains blocked, identify the root bridge as reported in the message, and configure a priority for the VLAN spanning tree so that it is not selected as the root. There could be other superior PVST+ roots (lower bridge ID, lower path cost, and so forth) than the message shows, and the port does not recover until all such roots are cleared. If you are unsure, disable and re-enable the port.

Error Message    SPANTREE-2-RECV-1Q-NON-1QTRUNK: Received 802.1Q BPDU on non 802.1Q 
trunk [chars] [chars].

Explanation    This message means that the listed interface on which a Shared Spanning Tree Protocol (SSTP) BPDU was received was in trunk mode but was not using 802.1Q encapsulation. The first [chars] is the port, and the second [chars] is the VLAN.

Recommended Action    Verify that the configuration and operational state of the listed interface and that of the interface to which it is connected are in the same mode (access or trunk). If the mode is trunk, verify that both interfaces have the same encapsulation (ISL or 802.1Q). If the encapsulation types are different, use the switchport trunk encapsulation interface configuration command to make them consistent. When the encapsulation is consistent, spanning tree automatically unblocks the interface.

Error Message    SPANTREE-2-RECV-BAD-TLV: Received SSTP BPDU with bad TLV on [chars] 
[chars].

Explanation    This message means that the listed interface received a Shared Spanning Tree Protocol (SSTP) bridge protocol data unit (BPDU) without the VLAN ID tag. The BPDU is discarded. The first [chars] is the port, and the second [chars] is the VLAN that received the SSTP BPDU.

Recommended Action    Find out more about the error by using the show tech-support privileged EXEC command and by copying the error message exactly as it appears on the console or system log and entering it in the Output Interpreter tool. Use the Bug Toolkit to look for similar reported problems. For more information about these online tools and about contacting Cisco, see the "Error Message Traceback Reports" section for more information.

Error Message    SPANTREE-2-RECV-PVID-ERR: Received BPDU with inconsistent peer vlan id 
[dec] on [chars] [chars].

Explanation    This message means that the listed interface received an SSTP BPDU that is tagged with a VLAN ID that does not match the VLAN ID on which the BPDU was received. This occurs when the native VLAN is not consistently configured on both ends of an 802.1Q trunk. [dec] is the VLAN ID, the first [chars] is the port, and the second [chars] is the VLAN.

Recommended Action    Verify that the configurations of the native VLAN ID are consistent on the interfaces on each end of the 802.1Q trunk connection. When the configurations are consistent, spanning tree automatically unblocks the interfaces.

Error Message    SPANTREE-2-ROOTGUARD_BLOCK: Root guard blocking port [chars] on 
[chars].

Explanation    This message means that on the listed interface a BPDU was received that advertises a superior spanning-tree root bridge (lower bridge ID, lower path cost, and so forth) than that in use. The interface is put into blocking state and marked as root-guard inconsistent to prevent a suboptimal spanning-tree topology from forming. The first [chars] is the name of this port, and the second [chars] is the spanning-tree instance on which this port was blocked.

Recommended Action    Enter the show spanning-tree inconsistentports privileged EXEC command to review the list of interfaces with root-guard inconsistencies. Determine why devices connected to the listed ports are sending BPDUs with a superior root bridge, and take action to prevent more occurrences. When the inaccurate BPDUs have been stopped, the interfaces automatically recover and resume normal operation. Make sure that it is appropriate to have root guard enabled on the interface.

Error Message    SPANTREE-2-ROOTGUARD_CONFIG_CHANGE: Root guard [chars] on port [chars] 
on [chars].

Explanation    This message means that the spanning-tree root guard configuration for the listed interface has changed. If enabled, any BPDU received on this interface that advertises a superior spanning-tree root bridge (lower bridge ID, lower path cost, and so forth) to that already in use causes the interface to be put into the blocking state and marked as root-guard inconsistent. The first [chars] is the root-guard state (enable or disable), the second [chars] is the interface, and the third [chars] is the spanning-tree instance.

Recommended Action    Verify that this is the desired configuration for the listed interface. Correct it if it is not the desired configuration; otherwise, no action is required.

Error Message    SPANTREE-2-ROOTGUARD_UNBLOCK: Root guard unblocking port [chars] on 
[chars].

Explanation    This message means that the listed interface is no longer receiving BPDUs advertising a superior root bridge (lower bridge ID, lower path cost, and so forth). The root-guard inconsistency is cleared for the interface, and the blocking state is removed from the interface. The first [chars] is the name of this port, and the second [chars] is the spanning-tree instance on which this port was blocked.

Recommended Action    No action is required.

Error Message    SPANTREE-2-UNBLOCK-CONSIST-PORT: Unblocking [chars] on [chars]. Port 
consistency restored.

Explanation    This message means that the port VLAN ID or port type inconsistencies have been resolved and that spanning tree will unblock the listed interface of the listed spanning-tree instance as appropriate. The first [chars] is the interface, and the second [chars] is the spanning-tree instance.

Recommended Action    No action is required.

Error Message    SPANTREE-3-BAD_PORTNUM_SIZE: Rejected an attempt to set the port 
number field size to [dec] bits (valid range is [dec] to [dec] bits).

Explanation    This message means that an error caused the platform-specific code to request more or fewer bits than are allowed. The spanning-tree port identifier is a 16-bit field. That is divided evenly between the port priority and port number, with each subfield being 8 bits. This allows the port number field to represent port numbers between 1 and 255. However, on systems with more than 255 ports, the size of the port number portion of the port ID must be increased to support the number of ports. This is performed by the STP subsystem at system initialization because the maximum number of ports on a particular platform does not change. The first [dec] is the number of bits for the port number, and the second and third [dec] describe the valid range.

Recommended Action    Copy the message exactly as it appears on the console or in the system log. Research and attempt to resolve the error by using the Output Interpreter. Use the Bug Toolkit to look for similar reported problems. If you still require assistance, open a case with the TAC, or contact your Cisco technical support representative, and provide the representative with the gathered information. For more information about these online tools and about contacting Cisco, see the "Error Message Traceback Reports" section.

Error Message    SPANTREE-3-PORT_SELF_LOOPED: [chars] disabled.- received BPDU src mac 
[enet] same as that of interface.

Explanation    This message means that a BPDU was received on the listed interface with a source MAC address that matches the one assigned to the listed interface. This means that a port might be looped back to itself, possibly because of an installed diagnostic cable. The interface will be administratively shut down. [chars] is the interface that received the BPDU, and [enet] is the source MAC address.

Recommended Action    Check the interface configuration and any cable connected to the interface. When the problem is resolved, re-enable the interface by entering the no shutdown interface configuration command.

Error Message    SPANTREE-4-PORT_NOT_FORWARDING: [chars] [chars] [chars] [chars] 

Explanation    This message means that the port is not forwarding packets; that is, it is not in a forwarding state. The first [chars] is the error severity. The second [chars] is the port. The third [chars] is the interface. The fourth [chars] is the status of the interface.

Recommended Action    Find out more about the error by using the show tech-support privileged EXEC command and by copying the error message exactly as it appears on the console or system log and entering it in the Output Interpreter tool. Use the Bug Toolkit to look for similar reported problems. For more information about these online tools and about contacting Cisco, see the "Error Message Traceback Reports" section for more information.

Recommended Action    Copy the error message exactly as it appears on the console or in the system log, call your Cisco technical support representative, and provide the representative with the gathered information.

Error Message    SPANTREE-5-EXTENDED_SYSID: Extended SysId [chars] for type [chars].

Explanation    This message means that the extended system ID feature is either enabled or disabled for the given type of spanning tree. If enabled, the spanning-tree instance identifier is stored in the lower portion of the bridge ID priority field and limits the allowed values for the bridge priority from 0 to 61440, in increments of 4096. If disabled, the bridge ID priority field consists only of the configured priority, but some spanning-tree features might not be available on a given platform (for example, support for 4096 VLANs). On some platforms, the extended system ID feature might be mandatory. The first [chars] is the extended system ID state (enable or disable), and the second [chars] is the spanning-tree instance.

Recommended Action    No action is required.

Error Message    SPANTREE-6-PORT_STATE: Port [chars] instance [dec] moving from [chars] 
to [chars].

Recommended Action    Verify that the configuration and operational states of the listed interface and those of the interface to which it is connected are in the same mode (access or trunk). If the mode is trunk, verify that both interfaces have the same encapsulation (ISL or 802.1Q). When these parameters are consistent, spanning tree automatically unblocks the interface.

Error Message    SPANTREE-7-RECV-1Q-NON-TRUNK: Received 802.1Q BPDU on non trunk 
[chars] [chars].

Explanation    This message means that an SSTP bridge protocol data units (BPDU) was received on the listed interface, which is not an operational trunking interface. The first [chars] is the port name, and the second [chars] is the VLAN name.

Recommended Action    Verify that the configuration and operational state of the listed interface and that of the interface to which it is connected are in the same mode (access or trunk). If the mode is trunk, verify that both interfaces have the same encapsulation (none, ISL, or 802.1Q). When these parameters are consistent, spanning tree automatically unblocks the interface.
