There is a MIB table to help you.

If you snmpwalk down ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName (AKA 
. you can get the mod/port names for each index. 
Here's the starting list from one of my switches:

ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.1 = sc0
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.2 = sl0
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.3 = 1/1
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.4 = 1/2
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.5 = 15/1
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.103 = VLAN-1
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.104 = VLAN-1002
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.105 = VLAN-1004
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.106 = VLAN-1005
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.107 = VLAN-1003
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.108 = VLAN-10
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.109 = VLAN-15
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.208 = VLAN-2
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.401 = 9/1
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.402 = 9/2
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.403 = 9/3
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.404 = 9/4
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.405 = 9/5
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.406 = 9/6
ifMIB.ifMIBObjects.ifXTable.ifXEntry.ifName.407 = 9/7

I query these and then store them in a perl hash and then use them in my CGI 
scripts whenever I need to translate Mod/Port <-> Index.
