Unable to discover SNMP Devices running classification for Unix and Http

[Prahlad Kumar]

Hello Everyone,

I'm facing an issue when running discovery for SNMP devices Nokia Switch - Model(SR Linux).

A) SNMP credentials are validated
B) Firewall opened
C) Open 161 is opened

Now the issue here is SNMP not classified properly and, 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?

Discovery Log:

Short Message	Source
Active, couldn't classify, now finished	Unix Classify
Active, couldn't classify, now finished	SNMP

ECC Queue:

Could you please assist me with what might be the issue?

Thanks

Prahlad Kumar

I'd bet it's a device running Net-SNMP as its snmp agent. A lot of different kinds of devices use that and return a sysDescr with PEN 8072 (eg, 1.3.6.1.4.1.8072.3.2.10 for the Linux version of Net-SNMP). Because different kinds of device can return the same value, it can't be used for classification. This is described in KB0751287.
