Receiving error on sensors for Netgear GS108T

Votes:

0

I am trying to monitor Netgear GS108Tinterfaces however I am getting error on some sensors.

For Sensor (003) Slot: 0 Port: 3 Gigabit - Level RMON (and Traffic), I get the following error: SNMPERR_BAD_SEC_NAME (SNMP error # -27).

The switch configuration for SNMP v3 does not have an entry for the user name for authentication, it uses the administration login password which does not have a username, would that be the issue?

Hello,

Based on the error message, the current SNMP settings for the device do not fit. You can find them in the "Settings" tab of the device in PRTG. If you are using SNMPv3 you need to enter a username.

You can also switch to SNMP v2 for testing purposes and adjust the settings in PRTG. Is it working then?

You can also test SNMP functionality with our SNMP Tester.

Kind Regards,
