Spanning Tree Unchanged When Port State Has Changed
If the show spanning tree CLI command still displays the same information while a port state has changed
then the problem could be due to a broken communication path between the CMM and NI. In this case do
the following (for both the CMM and NI):
• Time-out trace of the socket handler (stpNISock_totraceprint or stpCMMSock_totraceprint).
• Warning trace of the socket handler (stpNISock_warningprint or stpCMMSock_warningprint).
• Event trace (stpni_traceprint and stpCMM_traceprint).
• Board-up trace (stpNISock_boardupprint or stpCMMSock_boardupprint).
Other Cases
For analysis of Spanning Tree on an NI do the following:
• Event trace (stpni_traceprint).
• Dump the port trace (stpni_debugport).
• Time-out trace of the socket handler (stpNISock_totraceprint or stpCMMSock_totraceprint).
• Warning trace of the socket handler (stpNISock_warningprint or stpCMMSock_warningprint).
• Inter-NI trace: (stpNISock_intraceprint).
• Boards seen alive by the Socket Handler (stpNISock_boardupprint or
stpCMMSock_boardupprint).
