Any way of debugging SNMP v3 queries ?

[fjca]

Hello all,

We are moving from SNMP v1 to SNMP v3 on our network gear, and for some models, we cannot get SNMP v3 to work. This is happening both on Alcatel gear (OS9700, OS6450) and Cisco gear (C2960X). It is NOT a ACLs/permissions problem, since we can query the hosts from the Lansweeper server, using a third party tool (Snmpwalk from Snmpsoft).

Is there a way we can get some more logging/debugging for SNMP queries ?

DeviceTester only says :

"Scanning SNMP..
SNMP disabled or wrong community
Scanning VPRO RMCPPing.."

I would recommend trying an snmpwalk of 1.3.6.1.2.1.1. Lansweeper uses 1.3.6.1.2.1.1.2 to determine whether SNMP is working correctly. If the device does not return a valid output for this OID, SNMP scanning will be skipped.

If you require further assistance, contact support@lansweeper.com and provide:

• Program Files (x86)\Lansweeper\Service\Errorlog.txt, as present on your Lansweeper server.
  
• Screenshot of the entire Devicetester.exe output for 1 problem device. Perform the test from your Lansweeper server.
  
• Output of the other SNMP tool for the same device. Again, perform the test from your Lansweeper server.
