Chapter 5 Troubleshooting
The following is a list of typical troubleshooting techniques that can be used to determine
and correct a problem.
5.1 No Response from SNMP Agent
If the applications are showing the error "No Response from SNMP Agent", verify the
following:
1. That the CanogaView Smart Element Manager Web Server's address is
entered into the SNMP Agent's (DMM's or 9135/40, etc.) host table. The
SNMP agents will only respond to those IP addresses listed in its host table.
2. That the Agent's Default Gateway field is set correctly. A correct Default
Gateway is required in a routed environment to ensure that IP connectivity is
possible from the SNMP Agent to the CanogaView Smart Element Manager
Web Server.
3. That you can Ping the SNMP Agent from the CanogaView Smart Element
Manager Web Server and vice versa.
4. That you can Telnet to the SNMP Agent from the CanogaView Smart
Element Manager Web Server.
5. From the CanogaView Smart Element Manager Web Server, try running
running traceroute to trace the route from the CanogaView Smart Element
Manager Web Server to the SNMP Agent. Failures can indicate a problem
with a router setup or the Default Gateway setting on the Agent.
6. Verify the correct SNMP Community names are being used within the Agent
Chooser and match those in the SNMP Agent's System Configuration
parameters.
7. If you have access to a SNMP Mib Browser software, see if you can access
the SNMP Agent.
8. If you have access to a protocol analyzer, monitor the connection to see if
any SNMP traffic is present for these IP addresses.
9. Try resetting the SNMP Agent.
10. Contact Technical Support.
