[mrtg] Re: Measuring traffic by IP

[Pete Templin]

To do this, you'll need a device capable of getting in the middle and opening up packets to layer 3 and collating that data.  It's not a router function (by nature, but some routers can handle this sort of traffic accounting with companion network monitoring stations), and it's not a switch function (switches don't disassemble packets to layer 3).  SNMP can only provide the data available natively, so it's not an SNMP thing.

Your best bet is to change your goal.  Purchase an SNMP-manageable switch, and assign each "branch" to its own switch port.  Then monitor the traffic per port.

Subject: [mrtg] Measuring traffic by IP

  Hi guys,

 I am using MRTG to monitor my traffic flow in seven branches.

 When a branch is consuming all of the band, usually there is
a station that is the responsible for that.

  I would like to quantify the traffic that flows between
every station and the local router (to see which are
the great consumers).

  Is it possible with MRTG?

  Does anybody know some free software capable to do this
activity?

                              Regards,
                          Paulo R. Prista
