Is "ip flow egress" supported on this platform? Is it possible to collect bidir stats if Netflow configured as follows:
interface vlan ...
ip flow ingress
ip flow egress

Rather, it depends on the version of the IOS you're running:
http://www.cisco.com/en/US/docs/ios/netflow/command/reference/nf_01.html#wp1012951
" If your router is running Cisco IOS release 12.2(14)S or a later release, or Cisco IOS Release 12.2(15)T or a later release, NetFlow accounting might be enabled through the use of the ip flow ingress command instead of the ip route-cache flow command.
12.3(11)T
The egress keyword was added."
Unless there's new advances, I don't think you can apply both "ingress" and "egress" on the same interface. NetFlow is based on unidirectional flow records.

Hi yjdabear,
are you sure that egress netflow is supported on 7600? Because I have configured "ip flow ingress" and "ip flow egress" on a sub interface. My collector can only read ingress data. I check using "show ip cache flow" and only see ingress flow. Also, take a look at this email thread http://puck.nether.net/pipermail/cisco-nsp/2007-July/041977.html. Cisco documentation sometimes is confusing that I often have doubts about them. Please if anybody can confirm?
Regards,
Prima
