Discovery SNMP devices - Getting 'Active couldnt classify'

[jasonbrough]

Getting some strange behaviour when discovering SNMP devices. In this case, I am trying to discover any switch / router device on a subnet. I have created a schedule using the 'SNMP only' behaviour and allocated the subnet range.

Taking a random device found on the network as an example, when I run the schedule it finds the device and tries to classify it but fails with 'Active couldnt classify'.

However, when I run a quick discovery against the device, it classifies it fine and the status changes to 'Update CI'. It is as though when running a schedule, it cant complete the classification properly. Any thoughts anyone?

*** I'm also seeing a lot of these:

SNMP probe timed out. Target is either unreachable or there are no valid credentials for it.

I'm assuming its a big ESX box as I see this in the XML:

Also it has 16 Intel Xeon CPU's. The question is how do I get the OID's beginnig 1.3.6.1.2 into the OID list in ServiceNow? I'm a bit confused coz I thought that these OID's are part of MIB2 which should already loaded into the MID server. But I cannot see any reference to that MIB in the agent\work\mibs folder:

If this is an ESX host it will be discovered through the vCenter API when we classify the process...If you want to build in an "ignore" identify the SNMP SYSOID and create a ESX Classifier with no identifier, this way it gets classified so no error but leaves the OOB processing of the device to the vCenter..

First of all check whether your SNMP device is enabled or not?

If not enable it, ask network administrator to enable that device, then do the discovery.

To check whether the selected SNMP device is enabled or disabled, just type the IP in any browser. ex if it is a printer

you'll see a network summary page for of your printer displaying the printer model name. Select Home tab and goto Network summary.

Down in the Enabled features block check the SNMP : Enabled or Disabled, mine is disabled from the below image you can see.
