I'm setting up Netflow and wanted to make sure I wasn't missing anything or If it could be setup in a better manner?
Router is 2801
Switch is C3560
IP flow export is version 9.
On the router I have one fastethernet port going to the high speed WAN connection, one serial port going to a backup T1 and the other fastethernet port is subdivided into two for the LAN (router on a stick) as we have two vlans for this site.
"ip flow-export destination 10.X.X.X 1055" I use SolarWinds to collect.
Then on the serial interface and the WAN interface I have "ip route-cache flow"
This feature is not turned on yet for the two LAN ports. I wanted to make sure there wasn't anything on the switch that I needed to setup? I couldn't find any commands on the switch related to netflow. When I add the "ip route-cache flow" on the LAN interfaces will my setup then be sound? As, I do want to capture traffic on both the WAN and LAN.
How taxing is it for a router to capture netflow data?
