When discovering Moxa Industrial switches (Moxa-EDS506P, and Moxa-ICS-G7826A), the ifAlias is blank. I believe this is because the MOXA SNMP oid is under enterprises private 1.3.6.1.4.8691.7.(162,199 respectively).
SNMPv2-SMI::enterprises.8691.7.99.1.1.0 = INTEGER: 26
SNMPv2-SMI::enterprises.8691.7.99.1.2.0 = STRING: "ICS-G7826A-20GSFP-4GTXSFP"
SNMPv2-SMI::enterprises.8691.7.99.1.4.0 = STRING: "V4.5.18 build 18041218"
....
SNMPv2-SMI::enterprises.8691.7.162.1.9.1.1.7.3 = STRING: "CAMERA"
SNMPv2-SMI::enterprises.8691.7.162.1.9.1.1.7.4 = STRING: "BROADBAND"
I would like to map this OID(portName) to the ifAlias field. but unsure where that is code hierarchy as the developing section for ports is still TBD.
Create new issue if required.
