Thanks, that document is very helpful.

Especially the section about "12.2(14)S having netflow subinterface
support", didn't know that, and ran into that barrier quite recently
on a 12.2(18)S router - the fun part is that it is accepted only
with "ip flow ingress" syntax, and not with "ip route-cache flow"
(while the physical interface understands "ip route-cache flow" just
fine).  Using "ip flow ingress" it works... nice.

Intersting, though, that neither 12.0S nor 12.2S get the "ip netflow
egress" feature.  12.0S has "MPLS egress netflow", so one would expect
"ip flow egress" to show up there eventually as well...

The usual problem with "T"error releases...
