That works but the mib entry is depricated.  The entry they want
you to use instead is:

Directory: ~ip/ipNetToMediaTable/ipNetToMediaEntry/ipNetToMediaPhysAddress

The "at" entry was put in the MIB with the implicit assumption
that no protocol other than IP would ever use ARP.  That's why
something different was needed.  My experience is that cisco
supports both.  Other router vendors do not.
