What does the error snmprealwalk(): No response from XXX.XXX.XXX.XXX mean?
(where XXX.XXX.XXX.XXX is the IP of your device)
This error is returned when Ubersmith cannot successfully poll your device via SNMP when one of a few conditions are occurring:
The appliance is no longer allowed access to the device via SNMP due to a change in the access control list on the device.
The SNMP communities on the device have changed and have not been updated in Ubersmith's Device Manager.
The device is no longer responding to SNMP requests in a timely manner due to its CPU being overloaded.
The appliance can no longer reach the device over the network.
The device is down.
Troubleshooting these conditions will likely correct the situation and reenable polling of your device. If you have continued difficulty even after reviewing these steps, please contact Ubersmith support.
