Flexible Netflow options

[it]

Hi Everyone,

I'm trying to gather netflow data over an IPSEC VPN and through my research I've learned that I need to configure Flexible Netflow.  However, I have a Cisco 2801 router with the latest ROMMON and IOS and the Flexible Netflow options aren't available. 

For instance:

flow exporter dwtmonitor

destination 10.0.16.172

source Loopback0

transport udp 2055

output-features

When I type "flow exporter <name>" it only allows me to enter "flow <name>" and there's no "destination" options or anything else.

ROMMON: 12.4(13r)T
IOS:  12.4(25d)

What am I doing wrong?

Hi,

FNF has been introduced in 12.4(9)T so 12.4 main line doesn't support it.

That was it - thanks for your help Laurent.  I guess I didn't understand that the latest firmware (12.4.25d) wouldn't necesserily have all the features before it.  But when I read up on Cisco versioning nomecalture it makes more sense that the firmware I was using was "stable" and the "T" is "unstable".  Thanks again.
