SPANTREE Messages

that you configure the interface to send prestandard MST BPDUs by using the spanning-tree mst

pre-standard interface configuration command. This warning message only appears once. [chars]

is the interface.

Recommended Action Use the spanning-tree mst pre-standard interface configuration command on

all the interfaces to which other switches running Cisco's prestandard MST version are connected.

We recommend that you migrate all the switches in the network to the IEEE MST standard version.

Error Message SPANTREE-4-PORT_NOT_FORWARDING: [chars] [chars] [chars] [chars].

Explanation This message appears when a port-not-forwarding alarm is set or cleared. The first

[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 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 require assistance, contact HP technical support and

provide the representative with the gathered information. For more information about the online

tools and about contacting HP, 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.

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.

Error Message SPANTREE-5-TOPOTRAP: Topology Change Trap for [chars] [dec].

Explanation
