Hi,
I configured netflow on cisco router 2921 and here is my config..
ip flow-export source Gigabitethernet 0/1
ip flow-export source Gigabitethernet 0/2
ip flow-export source Gigabitethernet 0/0
ip flow-export version 5
ip flow-export destination 131.x.x.x 2055
I also configure this on each interface
Interface Gigabitethernet 0/0
ip flow ingress
ip flow egress
ip route-cache flow
Interface Gigabitethernet 0/1
ip route-cache flow
Interface Gigabitethernet 0/1.55
ip flow ingress
ip flow egress
ip route-cache
Interface Gigabitethernet 0/1.56
ip flow ingress
ip flow egress
ip route-cache
Interface Gigabitethernet 0/2
ip flow ingress
ip flow egress
ip route-cache flow
when I performed show run on the router this is the configuration that appeared:
ip flow-export source Gigabitethernet 0/0
ip flow-export version 5
ip flow-export destination 131.x.x.x 2055
I noticed that the last source (Gigabitethernet0/0) that I typed was the source that was registered on the router
What could be the effect of this configuration?
Gigabitethernet0/1 and Gigabitethernet0/2 are on the public side of the router,I want to monitor the traffic that is going in and out of these interface because I have vpn tunnels configured on this interfaces (Gigabitethernet 0/1.55 and Gigabitethernet0/1.56)
Did I enter the right configuration for my router?
By the way my Solarwinds server resides on the Gigabitethernet0/0 network.
Please help..
Thank you very much!
