Switch Port Discovery Troubleshooting
If device polling fails, ensure that rules on the device allow polling from the NetProfiler or NetExpress. Also check the device is in the list of supported devices in
Switch Port Discovery Supported Routers and Switches. If polling still fails, you can enter the following CLI commands to verify SNMP communication and support.
For a lookup router, enter the command:
NetProfiler# snmpinfo <router-ip-address> --dev --fw --version <1|2> --comm <read-only-community-string>
For a switch, enter the command:
NetProfiler# snmpinfo router-ip-address> --dev --fw --version <1|2> --comm <read-only-community-string>
Command output includes information about whether or not the device is reachable and supported. You can give Riverbed Support the output of the command for additional information.
