SPANTREE Messages Chapter 2 Messages and Recovery Procedures Error Message SPANTREE-3-PORT_SELF_LOOPED: [chars] disabled.- received BPDU src mac ([enet]) same as that of interface. Explanation The listed interface received a BPDU 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 Verify the interface configuration, and test any cable connected to the interface. When the problem is resolved, re-enable the interface by using the no shutdown interface configuration command. Error Message SPANTREE-4-PORT_NOT_FORWARDING: [chars] [chars] [chars] [chars]. Explanation A port-not-forwarding alarm is set or cleared. The first [chars] is the mode, and the second [chars] is the severity. The third [chars] is the interface name, and the fourth [chars] is the alarm string. 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. For more information about these online tools and about contacting Cisco, see the "Error Message Traceback Reports" section on page 1-5. Error Message SPANTREE-5-EXTENDED_SYSID: Extended SysId [chars] for type [chars]. Explanation 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-5-ROOTCHANGE: Root Changed for [chars] [dec]: New Root Port is [chars]. New Root Mac Address is [enet]. Explanation The root switch changed for a spanning-tree instance. The first [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. Recommended Action No action is required. 2-62 Cisco ME 3400E, ME 3400, and ME 2400 Ethernet Access Switch System Message Guide OL-23408-01
