SPANTREE Messages
Error Message SPANTREE-3-PORT_SELF_LOOPED: [chars] disabled.- received BPDU src mac
([enet]) same as that of interface.
Explanation
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
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
[chars] is the mode (for example, assert or clear), and the second [chars] is the severity (for example,
minor). The third [chars] is the interface name, and the fourth [chars] is the alarm string (for
example, port not forwarding).
Recommended Action
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 SPANTREE-5-EXTENDED_SYSID: Extended SysId [chars] for type [chars].
Explanation
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
Error Message SPANTREE-5-ROOTCHANGE: Root Changed for [chars] [dec]: New Root Port
is [chars]. New Root Mac Address is [enet].
Explanation
[chars] and [dec] is the interface ID for the previous root port, the second [chars] is the interface ID
for the new root port, and [enet] is the Ethernet address of the new root port.
