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.

Hi Jason,

Could you tell me where should we increase the time out value for SNMP Probe. Also by doing so aren't you seeing the warning message "SNMP probe timed out. Target is either unreachable or there are no valid credentials for it" now. I am also seeing lot of warning messages as this in my instance.

Best Regards

Hi Kumar

Try this way

            Follow these instructions(may be it will be helpful)

1) first check the snmp is installed   or not in your system

2) check the snmp is enable/disable at target mission(if it is disable we cannot discover)

2) ask to your admin, is there any changed community string password(if it is not a public)

3) check the snmp devices are connected same network(some companies uses different networks for OS Devices and Network Devices)
