Chapter 7 MPLS VPN Solution Troubleshooting Guide
Provisioning Problems
a.Check to see whether it is disabled or starting. Initially, the CNGS Server is running.
b.Redeploy the service without doing an audit (this skips automatic audit saving time and complexity).
c.Find the state remaining in Invalid with 1) the error being “CORBA generated exception” and 2) CNGS Server is disabled or starting.
d.Go to the tmpdir (as given in netsys.tmpdir.unix in the csm.properties file) and see if you find a core dump.
e.If so, preserve the core file and both the PE’s and CE’s configuration files.
f.Tar the Repository at this stage (including the PE CE configurations) and submit the tar file along with the core fie to the Cisco Support Staff.
12.Question: When downloading router configuration files via Cisco IP Manager, how can I see exactly what is happening?
Answer: The best way is to turn on the Telnet trace for the Cisco IP Manager Network Element Manager server, or nem_server. You can do this while the Cisco IP Manager system is running by executing the following command (which is located on the Cisco IP Manager system in the Cisco IP Manager SRVRS directory):
setTelnetTraceOn
The output is displayed in the terminal window where the Cisco IP Manager system was started. You need to run this command only once. The command writes a trace flag into a configuration file for the nem_server expect scripts. The Telnet trace can also be logged to a file.
Start the Cisco IP Manager system as follows:
ipmgr.launch
For detailed information on configuring and starting Cisco IP Manager, refer to Chapter 3, “Installation and Configuration” in the Cisco IP Manager (Lite) User’s Guide, Version 2.0.
The Telnet trace is placed in the nem.trace file in the directory specified. On the MPLS VPN Solution system, you can use the Watchdog GUI to check the DIPM Server log file to monitor the uploading and downloading of router configuration files via the Cisco IP Manager nem_server. If more detail is needed, you can enable additional logging information by setting the property DIPMServer.debugLevel to 3 in the csm.properties file. For this to take effect, you must restart the DIPM Server.
