36 Cisco Systems Intelligent Gigabit Ethernet Switch Module for the IBM Eserver BladeCenter System Message Guide
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.
Response 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 , see the “Error Message Traceback Reports” section on page 9.
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.
Response 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.
SPANTREE-4-PORT_NOT_FORWARDING: [chars] [chars] [chars]
Explanation This message means that the port is not forwarding packets or is not in a forwarding state.
The first [chars] is the alarm ASSERT or CLEAR action. The second [chars] is the user-configured alarm
for this fault condition. The third [chars] is the interface.
Response 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 , see the “Error Message Traceback Reports” section on page 9.
Note: This message applies only to the Catalyst 2955 switch.
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.
Response No action is required.
