Re: [pysnmp-users] Problem observed in new mib loading

[<riv...@wi...>]

Hi,

The link you have pointed below is different one .

I am following this https://tools.ietf.org/html/rfc7666#section-6.1 RFC for VM-MIB.

Thanks & Regards,
Riva.

Looking at VM-MIB, I do not see vmNumber object there:

    http://mibs.snmplabs.com/asn1/VM-MIB

Do you have a newer MIB?

Also, given you query an existing object, you should query MIB object rather than MIB object instance:

    ObjectType(ObjectIdentity('VM-MIB', 'vmNumber', 0).addAsn1MibSource('file:///usr/share/snmp',
'http://mibs.snmplabs.com/asn1/@mib@')))
