Hello, all.
I'm a begineer and I have setup netflow at 6509 Native IOS. (IOS (tm) c6sup2_rp Software (c6sup2_rp-PK2S-M), Version 12.1(19)E1) and I have two questions.
1 . my 6509 config related netflow is below.
mls flow ip full mls nde sender
interface GigabitEthernet3/1
ip route-cache flow
ip flow-export version 5
ip flow-export destination 10.10.10.3 2060
I have read this site(http://www.crannog-software.com/netflowinstall.html ) written like this.
# mls aging long 300
if you leave the default of 900 seconds (15 minutes) you will get spikes in your utilization reports.
# mls aging normal 128
Note however that if you choose a value that is longer than 250 seconds NetFlow Monitor may report traffic levels that are too low.
question : all traffice is about 300M(with mrtg) but flow-tools say just about 200M, so I guess that this problem is related with that timeout, right?
If not, which config is required?
2. I have setup flow-tools at http://www.linuxgeek.org/netflow-howto.php
and I guess works well.But I can't find any AS information at flow files.
AS information is seen only at BGP enabled router?
3. I have one serial interface Gigabitethernet which is uplink and each server or other switch is connected with fastethernet interface. and VLAN is divided into VLAN10 and VALN20.
Then, which interface should do I execute "ip route-cache flow"?
only Gigabitethernet interface? or Vlan interface?
So thanks for your help in advance.
