Chapter 2 Messages and Recovery Procedures SPANTREE Messages 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. Error Message SPANTREE-2-ROOTGUARD_UNBLOCK: Root guard unblocking port [chars] on [chars]. Explanation 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 port name, 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-UNBLOCK_CONSIST_PORT: Unblocking [chars] on [chars]. Port consistency restored. Explanation 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. 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 An error occurred in the platform-specific code that caused 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 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 need assistance, open a case with the TAC, or provide your Cisco technical support representative with your information.

Messages and Recovery Procedures
SPANTREE Messages
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.
Error Message
SPANTREE-2-ROOTGUARD_UNBLOCK: Root guard unblocking port [chars] on
[chars].
Explanation
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 port name,
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-UNBLOCK_CONSIST_PORT: Unblocking [chars] on [chars]. Port
consistency restored.
Explanation
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. 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).
