Appendix A IPM FAQs and Troubleshooting Tips
Troubleshooting IPM
Q.
What does the “Responder On” field mean in Target Configuration?
A.
Rtr responder enables you to capture the jitter statistics, if you have enabled this feature on a device.
You can enable this feature from the router by using this command:
rtr responder
Rtr responder was introduced from SAA Version 2.1.1. In SAA 2.1.1, there was no MIB variable to
provide the status, so IPM captured the status as “Unknown”. From SAA version 2.2.0, the MIB
variable has been made available, so the status is displayed now as
Yes or No, depending on the
responder status.
If the target is not of type 'RTR responder,' then the field would give “N/A”.
Troubleshooting IPM
This section provides the troubleshooting information and FAQs for IPM application:
• IPM is not working after I upgraded my IPM servers to Release 2.6. Why?
• When I make changes to IPM components, how can I force IPM to detect the changes now, without
waiting for the next automatic poll?
• IPM is not accepting my timeout values for TCP Connect and DNS operations. Why?
• When IPM configures the routers, it seems that the configuration is a running configuration and not
saved. What happens when the router is rebooted?
• What if I lose a connection to a server?
• Why does IPM lock up sometimes when I’m running in a Web browser?
• Why won’t IPM let me delete one of my targets?
• If I see errors in graphs, what are some problems to look for?
• How do I change the IP address or host name of an IPM server?
• Why do I get an error message when I use a host name as a new IP address?
• Why do I get an error message when I use a host name as a new IP address?
• What if I accidentally create a collector that uses all remaining memory in the source router?
• I have a multi-homed machine. What should I do to make IPM work?
• How do I set debug levels of different IPM servers using Message Log server?
• How do I access the database directly?
• I am not getting any response from SA Agent Responder, how do I resolve this problem?
• What should I do when all DHCP IP Address Leases are Exhausted?
• What should I do when IP Path Echo Discovery Prevents IP Address Change?
• I am unable to launch the web client, and I get a Java console error message: “Reason = hostname
is not DNS resolvable.” What should I do?
• In the logs, I see the message “Unable to get version.” What does this mean?
• I have changed the date and time of my machine where I have installed the IPM Server. Do I need
to restart IPM?
