We use the “snmp-server chassis-id” field on all of our devices for internal inventory purposes. It would be great to have a field for something like “Internal ID” on the Overview tab if this data was populated. It comes back just as a simple string
The OID in question is 1.3.6.1.4.1.9.3.6.3 and it simply returns a string.
iso.3.6.1.4.1.9.3.6.3.0 = STRING: “SO12301”
