Topology Problems
Step 2 If the node table does not have the ipAddress set correctly:
• In Cisco MGM, since the node does not have any PNNI trunks and the persistent topology feature
is not enabled on this node, by default this node will be managed using the lan ip address. Verify if
this is the case.
Defect Information—Collect the following information for further analysis:
• Save ILMITopoc.log and topod.log
• Save the dump outputs of ILMITopoc, topod. The dump can be captured by issuing a kill -USR1
signal to the process.
• Collect the output of the switch CLI, selnd and dbnds.
Possible alternative workaround—None
C.4.2.4 Node Alarm Shown Incorrectly in Database
The node alarm state of a node is incorrect.
Step 1 Check the cache of topod and ILMITopoc.
Dump the cache of topod, ILMITopoc. This can be done by issuing a kill -USR1 to the process. From
the dump verify which process has the information incorrectly.
Step 2 If the node table does not have the node alarm status set correctly:
• Check the ILMITopoc.log file
• do an snmpget -c <community string> <ipAddress>1.3.6.1.4.1.351.110.1.1.14
This will return the alarm state of the node. 1 - Clear, 2- Minor, 3 - Major, 4- Critical
Defect Information—Collect the following information for further analysis:
• Save ILMITopoc.log, topod.log
• Save the dump outputs of ILMITopoc, topod. The dump can be captured by issuing a kill -USR1
signal to the process.
• Collect the output of the switch CLI, selnd and dbnds.
Possible alternative workaround—None
C.4.2.5 Reachable Node Is Shown as Unreachable
Node that is reachable from Cisco MGM is shown as unreachable on the Configuration Center, Chassis
View, Diagnostic Center or Statistics Report GUIs.
Step 1 If the node table has alarm state of this node as minor, major, critical or clear:
• Dump the cache of NMServer,Topod and ILMITopoc. To dump the cache issue a kill -USR1 signal
to the process. Check the dumps in the /opt/svplus/log directory and verify if the node alarm status
is correct in the cache dumps. If the alarm status is correct in the cache dump then open a new GUI
and check if the node shows in the correct alarm status in that GUI.
