>Many times a campus network will have a single border router which has
one interface pointing to the internal side and many interfaces pointing
to other providers.  These interfaces each have a unique numerical id
known in SNMP terms as an ifIndex.  The ifIndex to interface name mappings
can be determined by using a tool such as <SPAN
CLASS="APPLICATION"
>snmpwalk</SPAN
>
or using show commands in recent versions of IOS with the
'show snmp mib ifmib ifindex' or JunOS 'show interfaces'.  Once the ifIndex
for each interface is known flow-filter can be combined with flow-stat to
provide reports such as inbound vs outbound top src/destination IP
addresses.

Provide a top source IP address report by outbound traffic, ie the top
senders of traffic on the campus network.  Assume the ifIndex of the
campus interface is 5.</P
