Generic Troubleshooting in Dshell
Note. Dshell commands should only be used by Alcatel personnel or under the direction of Alcatel.
Misuse or failure to follow procedures that use Dshell commands in this guide correctly can cause lengthy
network down time and/or permanent damage to hardware.
The stp_help command (executed from the NiDebug Dshell command prompt) displays the trace menu
for the Spanning Tree algorithm on NIs. Enter stpNI_help at ???? at what? Text missing here. ????

These NI spanning tree trace utilities are described in the subsections that follow.
Event Trace (stpni_traceprint)
This trace includes the events received and generated by the Spanning Tree and the warning detected
while processing an event. A warning entry contains the name of the C source file and a line number. The
explanation of the warning can be given by Engineering.
Each event trace entry is built as follows:
• An ASCII pattern reflecting the event.
• Up to 4 parameters (a -1 (or 0xffffffff) indicates that the parameter is not significant).
The following is an example of the stpni_traceprint command printout:
