Switch Not getting discovered- Returning SNMP - Classify: 0 OIDs

[Surya Reddy2]

Hi,
I am trying to discover a Switch but It is Active, but couldn't get classified.
I get "SNMP - Classify: 0 OIDs" in the ECC queue.

However, When I test credentials for the IP Address of this Switch, It gets validated and also We are able to ping the Mid-Server from the Switch.
Please help.

Thanks,
Surya

This could potentially be related to SNMP session or request timing out. I’ve come across this issue with devices that are underpowered or return a large volume of OIDs for an SNMP query. Try changing the session and request timeout parameters values suggested by @dave hertel in the post below. https://community.servicenow.com/community?id=community_Question&sys_id=6741f6561be7fc10fc3233bc1d4bcbb3

Can you post the XML content of the input you highlighted.

Since SNMP CLassify Started --This probe mainly aims at extracting valid OID from the target device. 

Please post The Input payload for 'SNMP - Classify' .

Do you see these in INPUT PAYLOAD- 

• The 'sysDescr' tags define the type of device
• The 'sysObjectID' tag contains the OID.

I am suspecting something at Session or Firewall rules if any.

Hi Surya,

Make sure discovery ran on the same mid server on which you are able to validate the credential. In the discovery schedule record select "Use Behavior" for Mid Server selection method and select the "Network Devices (SNMP, SSH) record. In the behavior record you can see the related list containing entry for the Mid Server on which Discovery should run and the Functionality Definition.

Hope this helps.

Thanks
