netflow and IP route-cache flow on a serial Int?

Hi, i was wondring if turning the ip route-cache on a serial Int connecting to a T1 line to the ISP is having adverse affect on the router or not assuming more processing power.

is there a collector by Cisco thatcan be downloaded for free and use to collect the flow?

Can CiscoWorks LMS be used "or VMS" to collect the netflow information?

Thanks very much for your help/feedback.

Thx,

Masood

Masood,

Cisco have produced an excellent white paper on netflow performance - try searching for "NetFlow Performance Analysis".

Also, in the netflow section on Cisco's web site there is an extensive list of both commercial and freeware netflow applications. (You can't use CiscoWorks though.)

Andrew.
