If you look at the second packet of the attached capture, Wireshark considers this a malformed packet. As per RFC 1155 Section 3.1 The root node itself is unlabeled, but has at least three children directly under it: one node is administered by the International Organization for Standardization, with label iso(1); another is administrated by the International Telegraph and Telephone Consultative Committee, with label ccitt(0); and the third is jointly administered by the ISO and the CCITT, joint-iso-ccitt(2). This means that .0 is a valid OID and should be dissected correctly. net-snmp implemented this in a different way. For them .0 is a valid OID. #snmpwalk -On -v 2c -c public 10.125.224.111 1.3.6.1.2.1.47.1.1.1.1.3.1 .1.3.6.1.2.1.47.1.1.1.1.3.1 = OID: .0 Can someone provide some input on this?
