Does anyone know of a tool like Cflowd which will capture Netflow Type 7 stats? The only one I know of is the commercial product from Cisco; any advice would be greatly appreciated. ----------------------------------------------------------- Roland Dobbins <[email protected]> // 818.535.5024 voice -----Original Message----- From: Alex [mailto:[email protected]] Sent: Wednesday, July 26, 2000 8:23 AM To: David M.

We do about the same thing, but we store absolute byte counts, relative byte counts from the last measurement, and figure the kb/s; we also store AdminStatus and OperStatus for SLA purposes. > I'm concerned that the data is misleading, though, in that it will > include LAN broadcast traffic.

If they use the bandwidth, then they should pay for the bandwidth. > We've considered implementing unique customer VLANS to separate > customer broadcast domains, but it seems like that'd be a pain, > would eat up IP addresses, and possibly tax our routers with all of > the ISL/VLAN stuff? We do that; it's unwise to have everyone on the same VLAN, as some others have demonstrated.
