Actually, if you use a version of SNMP_utils.pm greater than 0.86, and can
perform snmp v2 calls, then &snmpwalk will use the snmpgetbulk routine,
which is much more efficient than determining which interfaces you need to
poll and then polling them in a single PDU.

So, try:
@inoctet = &snmpwalk('public at 172.16.0.1::::2','ifInOctets');

if you are really brave, you can try calling the getbulk process directly,
but that's not for the faint of heart.
