I am planning to use flow-stat for billing purpose but couldn’t understand
the syntax listed on flow-tag’s man page. If anyone has ever used this tool
fo billing purpose please help.
An example that shows our network setup follows:
One Cisco MSFC2 connected to Catalyst 6500 running hybrid software ( Cat OS
on the Supervisor , and IOS on the Routing Module i.e MSFC). Both have been
configured
to send netflow data to a Collector on UDP Port 9991. There are 55 Vlan
Interfaces configured on the Router which serves 55 subnets. The default
route to the internet
points from the MSFCs VLAN168 interface (IfIndex 52) to our internet
gateway. All other interfaces on it are subnets serving our Intranet users.
These users exchange data
with Servers on other subnets as well as have a direct (no-proxied) internet
access). My aim is to calculate how much traffice passed from one subnet to
the other (.ie
inter-subnet traffic that passes through the Router) and to bill the
Departments based on the aggregated IP data used (IP (no TCP or UDP info)
For intance
# Department Subnet MSFC-Router

IT 172.28.28.0/24 172.28.28.1/24

How should I configure the flow-tag to enable get the following output

I’d be very glad for your assistance
