Netflow configuration

Hi All,

When enable netflow on the router, need to put destination netflow collection ip address and port, could I put a network portion with subnet instead of specific ip address? Like:

ip flow-export destination 192.168.10.0 9991

instead of:

ip flow-export destination 192.168.10.10 9991

thank you,

Re: Netflow configuration

Hello Trina,

until some recent releases on some platform netflow export could be configured for a single host.

Some new releases have introduced the support of two hosts.

So I think the answer is that you need to specify the host ip address.

However, it could be interesting to think about using a directed broadcast destination address for example

192.168.10.255

but I don't think it is supported it would be a way to export to multiple hosts in the same subnet.

This could be possible because flow export are UDP unidirectional flows from router to collector device

Hope to help

Giuseppe
