No Data on Netflow

I've configured netflow to export data to a correct ip and port number. I doubled and tripled check both sides. And both show the the destination ip and port is ok. SNMP community is doubled check and everything on that side is ok. When I run the sho ip flow ex it comes up with 0's. Any suggestions?

Re: No Data on Netflow

You don't mention what device(s) or IOS versions you are running, but basically you need enter either of the following commands on each of your L3 interfaces.

ip route-cache flow

or

ip flow {ingress | egress}

Re: No Data on Netflow

I did the ip flow ingress egress and enabled the interface itself and everything worked great. thx

Re: No Data on Netflow

Hello,

could you send me your netflow configuration?

i.e.:

show running | inc flow

show running | inc mls

Kind regards,
