Egress NetFlow on 7600

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

Re: Egress NetFlow on 7600

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.

Re: Egress NetFlow on 7600

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
