Hello,

Please check if the SNMP Settings (Version, Community String, port, authentication) are correct. After that, please check if the corresponding PRTG Probe is allowed to send SNMP Requests to the device.

Please take a look at this article as well: My SNMP sensors don’t work. What can I do?

You can also use our SNMP Tester to test the SNMP-Functionality on the target device(s).


Kind regards,

HI Team,

I have checked the necessary steps. Its just this particular switch that is giving the error. Is there any other guidance you could give?

Hello there,

Hello there,

Please check SNMP configuration in the device. As long as you get this error, the device does not respond to SNMP requests. Some devices for example have a setting about which hosts are allowed to send them SNMP queries. You need to make sure that PRTG's IP (or from the remote probe that should run the sensor) is in this list.

Kind regards,

Erhard

Hi,

Could you guide me on the MIB part. I have the view internet and iso installed on of the AP and the uptime is successful. I want all the OID accessible. It would anyways be the readonly access.

Hi Team,

Is there a possibility to talk to one of the Engineers? We are using the corporate version of PRTG. I'm not able to proceed with this particular switch at all.

Hi there,

In this case I would recommend contacting the vendor's support. I'm afraid we cannot assist in setting up SNMP for a particular device.

Kind regards,

Erhard
