How does 'ip route-cache flow' and 'ip flow ingress' differ?

[jkeeffe]

This is on a 6509 IOS 12.2(18)SXE3 with CEF enabled. To get Netflow statistics I usually configure 'ip route-cache flow' on an interface, but the 6500 also includes the 'ip flow ingress' and 'ip flow egress' interface commands.

Should I be using the flow ingress and egress commands instead of route-cache flow, or all three of the commands, to get the best netflow statistics?

"ip route-cache flow" has been deprecated in 12.2(18)SXD. Use "ip flow ingress" with 12.2(18)SXF and later.
