Typically you need to "export" from at least two interfaces, unless your IOS supports "ip flow ingress" and "ip flow egress" on the same interface?
Network load is "accurate", although it doesn't distinguish between Tx and Rx :( ----- Original Message ----- From: [email protected] <[email protected]> To: [email protected] <[email protected]> Sent: Fri Apr 30 11:28:25 2010 Subject: Re: [Ntop] No data in Netflow on FreeBSD 7.0 Gary Gatten wrote: > I noticed something similar re the admin login.

I'm only exporting the Fe (on the base interface, not subs), since the multilink this is also natting, and the multilink is the nat outside.
