You just need the product specific MIB's. Download GETIF, which can be
found in the archives or any simple search engine, add the MIB to it and
Browse the MIB. Find the OID you want to use and place it on the Target
Line rather then the additions of individual ports. Of course all of
this is product specific.

An SNMP query is miniscule when run over an Ethernet LAN. When you start
querying 100+ routers from a single central site this may be a concern,
and require the distribution of the querying systems.
