How to get port description over SNMP on PowerConnect 5548

Hi All,

I am using PowerConnect 5548 firmware 4.1.0.8

I  want to get a port description configured over SNMP.

Ex:

SW conf:

interface gigabitethernet1/0/1
description testtest
spanning-tree portfast
switchport access vlan 172
!

I tried flowing oid's and i did not got required result:

1. IF-MIB::ifDescr.1 = STRING: gigabitethernet1/0/1

2. SNMPv2-SMI::enterprises.89.53.3.1.2.1 = STRING: "gi1/0/1"

Is there a way to get a description configured on port?
