This is not an "easy" port. You have to take many things into consideration,
|
|
what flow data to collect (disk space, etc), how and when to remove unneeded
|
|
flow files. And you have to know, what it is all about. If you don't know
|
|
Cisco NetFlow switching and its data export feature, then I recommend you
|
|
to deinstall this port.
|
|
|
|
Prerequisites:
|
|
A) You need to read the installation instructions closely, see:
|
|
${PREFIX}/share/doc/flowscan/INSTALL
|
|
|
|
B) You need to configure your Cisco Router, to enable Netflow Switching
|
|
and Netflow data export (version 5 flow export format).
|
|
|
|
PLEASE NOTE, YOU HAVE TO KNOW EXACTLY, IF YOU REALLY WANT TO ENABLE NETFLOW
|
|
SWITCHING ON YOUR CISCO CORE OR DISTRIBUTION ROUTERS, WHAT PERFORMANCE IMPACT
|
|
MIGHT BE INVOLVED WHEN DOING THIS, WITH THE GOAL, NOT TO LOOSE YOUR ROUTING/
|
|
SWITCHING PERFORMANCE. BE WARNED !!!
|
|
|
|
C) You need to configure SNMP on your Cisco Router.
|
|
|
|
Post-installation tasks involve:
|
|
a) Configure cflowd properly for your needs, see above mentioned docu !
|
|
Example files reside in ${PREFIX}/etc, files:
|
|
cflowd.conf.example and cfdcollect.conf
|
|
b) Configure flowscan, see above mentioned docu !
|
|
Example files reside in ${PREFIX}/var/db/flows/bin, files:
|
|
"foo".sample ...
|
|
c) Customize and install crontab file, example see:
|
|
${PREFIX}/share/doc/flowscan/crontab.sample
|
|
d) Activate flowscan startscript by renaming it as usual, see example in:
|
|
${PREFIX}/etc/rc.d/flowscan.sh.sample
|
|
e) Create graphs using make by customizing the sample Makefile, see docu !
|
|
${PREFIX}/var/db/flows/graphs/Makefile.sample
|
|
Please note, that the Makefile has to be reconfigured if you add
|
|
or remove protocols in ${PREFIX}/var/db/flows/bin/CampusIO.cf !
