is there a way to do multiple destinations on netflow data on interfaces? I'm trying to do this because we need to extract outside and inside. i am not finding any reference to it and it looks like i can't do it.
for the way Netflow builds the flow cache you might be able to export all records of flows to two destinations (if supported in your platform and IOS version/features set) but you cannot divide the interfaces to be monitored in two subsets and export the observed flows on the two to two different netflow collectors. Because this would require to create two different flow tables and this is not something that Netflow performs.
Hope to help
Not sure if you wanna do that, but if you want to export input to one destination and output to another one, you can create 2 flow exporter
interface Vlan558 ip flow monitor MONITOR_INPUT input ip flow monitor MONITOR_OUTPUT output flow exporter EXPORTER_PRTG_INPUT destination 192.168.1.1 source Loopback20 transport udp 10022 flow exporter EXPORTER_PRTG_OUTPUT destination 192.168.1.2 source Loopback20 transport udp 10022 !! ! flow monitor MONITOR_INPUT exporter EXPORTER_PRTG_INPUT flow monitor MONITOR_OUTPUT exporter EXPORTER_PRTG_OUTPUT
Don't know if it could be supported by your IOS, in exemple this is WS-C6506-E with adventerprisek9-mz.SPA.151-2.
But you can't export input or output to several destination.
Hope this helps,
