Unable to discover SNMP Devices(Active, Could't classify)

Hello Everyone,

Today I noticed a very weird issue when running discovery for SNMP devices.
A) SNMP credentials are validated
B) Firewall opened
C) Open 161 is opened
Now the issue here is I can see SNMP classified properly but rather than going to identification, it is again running classification for Unix and Http as attached and ended up with Active, Couldn't classify error. Could you please assist me with what might be the issue?

Thanks,

Sudhakar

Hi,

We usually have a SSH credentials try first and then SNMP as per order. And If the port 22 is open then it might try SSH as well. But after SNMP classification the device is not getting classified because of OID might not be there in classification criteria.

So check SNMP Classification criteria first.


Thanks,

Hi Sudhakar,

Are you using "Behavior" for the SNMP discovery? If so check the "Discovery Functionality" selected for that Behavior. Make sure "SNMP Only" is selected for "Functionality Definition". This makes sure not to trigger other classifiers other than SNMP.

 

Thanks

Hi Sandeep, I am not using Discovery behaviour.

Thanks Ashutosh, I forgot to validate that SNMP OIDs. I have added SNMP OID and worked fine.
