SPANTREE Messages

This section contains the spanning-tree messages.

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-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 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-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 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 PVST+ switch is connected to a Multiple Spanning Tree Protocol (MSTP) switch, the internal spanning-tree (IST) root (MSTOO) 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 indicates, 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. 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 an SSTP 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    If the message recurs, copy the 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-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 is 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 mode displayed in show spanning-tree privileged EXEC command.

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 mode displayed in show spanning-tree privileged EXEC command.

Recommended Action    No action is required.

Error Message    SPANTREE-2-RX-PORTFAST: Received BPDU on PortFast enabled port. 
Disabling [chars].

Explanation    This message means that a BPDU was received on the listed interface, which has the spanning-tree Port Fast feature enabled. Because spanning-tree BPDU guard is also enabled, the interface is administratively shut down. [chars] is the interface that received the BPDU.

Recommended Action    Verify the Port Fast configuration on the interface. If the Port Fast behavior is desired, verify that the interface is connected to only a host or router and not to a bridge or a switch. After resolving the conflict, re-enable the interface by entering the no shutdown interface configuration command.

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 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 occurred in the platform-specific code, which caused it to request more or less bits than are possible. The spanning-tree port identifier is a 16-bit field, which 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 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 will not change. This error occurs because of an error in the platform-specific code, which causes it to request more or less bits than are possible. 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 error message exactly as it appears on the console or in the system log. Enter the show version privileged EXEC command to gather data that might provide information about the error. If you cannot determine the nature of the error from the error message or from the show version command display, call your Cisco technical support representative, and provide the representative with the gathered information.

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 plugged into the interface. When the problem is resolved, re-enable the interface by entering the no shutdown interface configuration command.

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, this 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-7-BLOCK-PORT-TYPE: Blocking [chars] on [chars]. Inconsistent 
port type.

Explanation    This message means that the listed interface is being held in the spanning-tree blocking state until the port-type inconsistency is resolved. The first [chars] is the interface, and the second [chars] is the spanning-tree instance.

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. 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 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. When these parameters are consistent, spanning tree automatically unblocks the interface.

SPANTREE_FAST Messages

This section contains the spanning-tree fast-convergence message.

Error Message    SPANTREE_FAST-7-PORT_FWD_UPLINK: [chars] [chars] moved to Forwarding 
(UplinkFast).

Explanation    This message means that the listed interface has been selected as the new path to the root switch for the listed spanning-tree instance. The first [chars] is the spanning-tree instance, and the second [chars] is the interface.

Recommended Action    No action is required.

SPANTREE_VLAN_SWITCH Messages

The section contains the per-VLAN spanning-tree-specific message.

Error Message    SPANTREE_VLAN_SW-2-MAX_INSTANCE: Platform limit of [dec] STP instances 
exceeded. No instance created for [chars] (port [chars]).

Explanation    This message means that the number of currently active VLAN spanning-tree instances has reached a platform-specific limit. No additional VLAN instances will be created until the number of existing instances drops below the platform limit. [dec] is the spanning-tree instance limit, and the first [chars] is the smallest VLAN number of those VLANs that are unable to have STP instances created.

Recommended Action    Reduce the number of currently active spanning-tree instances by either disabling some of the currently active spanning-tree instances or deleting the VLANs associated with them. You must manually enable the spanning trees that could not be created because of limited instances.

STORM_CONTROL Messages

This section contains the storm control message.

Error Message    STORM_CONTROL-2-SHUTDOWN: Storm control shut down [chars].

Explanation    This messages means that excessive traffic has been detected on a port that has been configured to be shut down if a storm event is detected. [chars] is the physical interface.

Recommended Action    When the source of the packet storm has been fixed, re-enable the port by using the no shutdown interface configuration command.

SW_VLAN Messages
