SYNOPSIS

To execute CUFlow properly, type:

	flowscan CUFlow


OVERVIEW:

CUFlow.pm is a FlowScan (http://net.doit.wisc.edu/~plonka/FlowScan/)
module designed to combine the features of CampusIO and SubNetIO as we
needed them and also hopefully process data more quickly.  CUFlow
allows you to differentiate traffic by protocol, service, TOS, router,
and network and then generate TopN reports over 5 minutes periods and
over an extended period of time.  CUGrapher is the companion graphing
tool and is designed as a CGI which generates images on the fly based
on user input with data supplied by CUFlow.

INSTALLATION AND EXECUTION:

Follow the instructions for installing FlowScan
(http://net.doit.wisc.edu/~plonka/FlowScan/INSTALL.html) If you are
only using CUFlow and not the other modules distributed with FlowScan
then you probably don't need to install ksh and the Boulder and
ConfigReader Perl modules.

CUFlow.pm and CUFlow.cf should be placed in the $flowscan_home/bin
directory along with the other modules.  To use CUFlow add it to the
Report section of flowscan.cf and fire up flowscan.  For more detailed
information on the format of CUFlow.cf see the perldoc documentation.

CUGrapher.pl should be placed in your cgi-bin and the Local Settings
section should be checked to make sure the values make sense for your
site.  You will most certainly need to change $rrddir and
$organization.  The other settings should be reasonable defaults and
should be self-explanatory.

KNOWN ISSUES:

If you are not using a Cisco Catalyst 6509, you will want to uncomment
lines 495 and 496.  These lines deal with the fact that the 6509
doesn't fill out the NextHop and OutputInterface fields in the NetFlow
records sent from the PFC.
