Cisco Systems added this new feature in these releases:

12.0(19)S This feature was introduced on the Cisco 12000 Internet router.
12.0(19)ST This feature was integrated into Cisco IOS Release 12.0(19)ST.
12.2(2)T This feature was integrated into Cisco IOS Release 12.2(2)T.

With this new feature you can add up to two different destinations to
collect the Netflow statistics.
This is usefull if you want to have a master and a backup collectors, so if
the primary collector fails you can keep receiving the flows with the second
one.
The overhead introduced it's minimum, only there's more traffic. The router,
in any case, needs to maintain and process the netflow information.

I hope this information could be useful to flowscan users.

Albert.
