Problem Clarification

The SNMP query for g450/g430 interface description does not contain the interface label, in the gateway config file it is the "description" keyword value. User would like to get this value also by SNMP query.

example:
gateway configuration:

!
interface Vlan 1
description "AvayaVlan"
icc-vlan

Now running the SNM query on the ifDescr object only shows:

snmpwalk -v 1 -c public 135.124.xxx.xxx IF-MIB::ifDescr.211841025
IF-MIB::ifDescr.211841025 = STRING: Avaya Inc., G450 Media Gateway, Vlan, Vlan 1

The MIB definition of the ifDescr is:

          ifDescr OBJECT-TYPE
              SYNTAX DisplayString (SIZE (0..255))
              ACCESS read-only
              STATUS mandatory
              DESCRIPTION
                      "A textual string containing information about the
                      interface. This string should include the name of
                      the manufacturer, the product name and the version
                      of the hardware interface."

And this is exactly what the response contains.

Cause

Working as designed. The "IF-MIB::ifDescr" MIB object does not contain the interface description label.

Solution

Use this MIB OID to get the interface description:
1.3.6.1.4.1.6889.2.1.6.2.2.1.1.6

Using the example from above:
snmpwalk -v 1 -c public 135.124.xxx.xxx 1.3.6.1.4.1.6889.2.1.6.2.2.1.1.6.211841025
SNMPv2-SMI::enterprises.6889.2.1.6.2.2.1.1.6.211841025 = STRING: "AvayaVlan"
