I am experiencing an anomaly with NETFLOW right now
and want to see if anyone out there has the same problems
so we can compare notes. I have a ticket open with the
TAC on this and have been fighting this bug since 11.2.7P.

I have a 7507 that is configured with these componenets:
 1 AIP controller (1 ATM).
 1 VIP2 controller (2 HSSI).
 2 HSSI network interface(s)
 1 ATM network interface(s)
I am currently running image 'rsp-jsv-mz.112-9.P.bin'.
Simple router, just LANE, SMDS, and Frame.

The LAN Interfaces are sub-interfaces ATM1/0.1 (.2, .3)
which are LANE clients.

The WAN Interfaces are in two flavors. SMDS and Frame.
Again, they are also sub-interfaces that are numbered
with IP addresses.

My point here is that all of my active (numbered) interfaces
are sub-interfaces and because I can't place the
'ip route-cache flow' command on the acual sub-interface,
I can't get NETFLOW information from those sub-ints.

* Why can't I put the 'ip route-cache flow' command
on the sub-interface? *

I did and ip fowarding between my SMDS sub-ints and
ATM sub-ints stopped. A call to the TAC informed me
that I can only place the 'ip route-cache flow' on my
"Parent" interfaces and to keep them off my sub-interfaces
until this issue is resolved.

Anyone out there see this same type of problem?
