Hello,
Thank you for your message.
According to the message you get, the device doesn't return data to the requests executed by the probe. This can be due to a firewall on the network, invalid SNMP credentials configured in the device settings or the device takes a long time to reply.
Therefore, I invite you to test the SNMP configuration by executing a Read Device Uptime request with SNMP Tester, from the corresponding probe server (on which the device is configured).
How to use the tester:
- Start the SNMP Tester
- Configure the tester below point "1. Set SNMP Settings"
- Local IP = Any (at first). If this fails, also switch to one of the listed local IPs
- Device IP/Port = IP of the target device and the configured port (SNMP uses port 161 by default)
- SNMP Version = Select the version which is configured on the device
- Community = Community string defined in the target device
- Below "Select Request Type", switch to the option "Read Device Uptime"
- Press the "Start" Button on the top
Do you get the same error in the result provided by the tool ? If that's the case, I invite you to make sure that the SNMP settings you use and configured in PRTG correspond to those set on your device.
Regards.
