IP FLOW EGRESS on 7600

Hello Allan,

according to netflow command reference only ip flow ingress is supported on C7600

see

http://www.cisco.com/en/US/docs/ios/netflow/command/reference/nf_01.html#wp1012951

Cisco 7600 Series Platforms

The ip flow ingress command is supported on the Supervisor Engine 720 in PFC3B and PFC3BXL mode.

The ip flow ingress command is supported on the Supervisor Engine 2 with a PFC2.

In Release 12.2(18)SXF and later releases, to create a NetFlow entry, you need to enter the ip flow ingress command. In releases prior to Release 12.2(18)SXF, the NetFlow entries are created automatically. 

Hope to help

Hello Allan,

according to Feature Navigator the feature Netflow egress accounting is supported on C7600 in more modern releases like 15.0S - 15.2S they require moving to the licensing model.

see

do search by feature

type Netflow select filter then scroll down the features until you find Netflow egress accounting use add button in the middle then continue on the far right

Hope to help

IP FLOW EGRESS on 7600

Hi,

It seems 7600 platform do not support Egress Netflow. TAC engineer said its not going to work even changing IOS, thogh I am not sure about upgrading SUP. I was able to configure "ip flow egress" but no egress flows were visible and exported to collector.

Please refer this URL which says no support for egress netflow.

IP FLOW EGRESS on 7600

Hello Arun,

you are right 15.0S configuration guide for C7600 does not mention ip flow egress

see

http://www.cisco.com/en/US/docs/routers/7600/ios/15S/configuration/guide/nde.html#wp1131072

I would say that feature navigator is wrong about Netflow egress accounting on C7600 it says supported in 15.0S -15.2S

Hope ot help

Giuseppe
