Right, it only shows the packets that were not cut-through switched. The only way to get all of the traffic is with netflow, and that's an whole other breed of cat... The real question is - why do you care? Monitoring based on the port is generally more interesting than on the vlan, unless you want all of the net-flow data. > > > -----Original Message----- > > From: Distribution Lists [mailto:[EMAIL PROTECTED] > > I need some help graphing VLAN traffic on a 6509. > > From what I have read, the counters that represent VLAN ip traffic is > > misleading ?

There is no "maximum" in cut-through mode, other than the backplane of the switch (either 32Gb/s or 256Gb/s, depending on whether the cross-bar feature is set up for your hardware) so you can't use the information to determine when the resource is going to be exhausted... 2. set up flow-tools (http://www.splintered.net) and get really detailed records that tell you everything, but that don't summarize into tidy graphs. -- Daniel J McDonald, CCIE 2495, CNX Austin Energy -- Unsubscribe mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/mrtg FAQ http://faq.mrtg.org Homepage http://www.mrtg.org WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
