Hi, I've a customer running on the mentioned core switch with software of c6msfc2-pk2sv-mz.121-13.E11. I'm implementing a netflow collector into their environment, but it turn out that this version of IOS only support netflow v5/v6, and with only fast-switching flow-cache supported.
My initial plan is as follows:
ip flow-export destination < >
ip flow-export source < >
ip flow-export version 5
interface vlan <server_vlan>
ip route-cache flow.
what's the main difference between "ip route-cache flow" and "ip flow ingress/egress".
Does server -> server in the same vlan consider a flow as well?
unfortunately "ip route-cache flow" is the only option in that particular IOS, I just wondering is there anything I miss using "ip route-cache flow" instead of "ip flow ingress/egress". And is it possible to enable the netflow for the layer2-switched traffics using the "ip route-cache flow"?
I've spoke to the customer but they're reluctant to upgrade their current working IOS due to various reasons. I've conducted some other netflow collection using the "ip route-cache flow" but the end-result was not really satisfying/acceptable as the result does not seem to reflect the actual traffics.
well, decided not to send the layer2 switched traffic through netflow, only account for the layer3 switched traffics. So only the "ip route-cache flow" command and the ip flow-export commands are required.
I've done this better and think was not the best way as the collected result does not seems to reflect the actual traffics...just wondering whether there's another way to do this without upgrading their current IOS?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
