How can a network device's Sys Object ID (OID) be identified from an SNMP walk?
ITMS 8.x
After a walk is completed, the OID returned from .1.3.6.1.2.1.1.2.0 will provide the devices specific OID to be used.
For example the first two lines from a walk show:
.1.3.6.1.2.1.1.1.0 = STRING: "Linux SOCC-CPSG5100-1 2.6.18-92cpx86_64 #1 SMP Fri Apr 7 13:55:39 IDT 2017 x86_64"
.1.3.6.1.2.1.1.2.0 = OID: 1.3.6.1.4.1.2620.1.6.123.1.66
By looking under .1.3.6.1.2.1.1.2.0 for any device, the result will be that device's sys Object ID (OID).
