Why not use the MIB-II tree?
1.3.6.1.2.1.2.2.1.2 will give you the same information as above, i.e.
"FastEthernet0/0" and so on...
The ifIndex for that particular interface can be returned as part of the
OID.
I suspect that using the OIDs you have above is only worthwhile if 1.
your device is running CDP and 2. it's not explicitly disabled on certain
interfaces.
Hope this helps
