Hmm..in my experience, a MIB will include an ARP table, from
which you can determine who's actually sent *any* packets in
the last (ARP cache expire interval); I don't know, however,
of any way to get traffic data on non-SNMP hosts without
logging all packets and analyzing the logfile.
That said, of course, my router is a Cisco, so YMMV.
