ip route-cache command missing (Cisco IOS 12.2)

Hello All!

I have looked around Google and the forums here with no luck and I am hoping that an expert out there might be able to assist me. We are preparing to test SolarWinds out and I needed to configure NetFlow on our 7606 router. I was following the instructions presented by the video at this link:

www.solarwinds.com/.../RTNA_how_to_Configure_NetFlow.aspx

I ran the following commands which all worked and I had no problems at all:

ip flow-export source gi2/15

ip flow-export version 5

ip flow-export destination 10.11.12.13 2055

This is where the honeymoon ended :-) Upon entering the interface mode to designate the interfaces I would like to capture NetFlow data for I attempted to run the following commands and it doesn't exist:

ip flow ingress

ip flow egress

ip route-cache flow

I ran the following "ip ?" to see what the problem was and the only options I have are the following:

myrouter(config)#int gi2/4
myrouter(config-if)#ip ?
Interface IP configuration subcommands:
access-group Specify access control for packets
address       Set the IP address of an interface
arp           Configure ARP features
dhcp          DHCP
rsvp          RSVP interface commands
rtp           RTP parameters
vrf           VPN Routing/Forwarding parameters on the interface

I am running the following IOS with the SUP720:

I looked all over the Cisco site (as I suspect it might have something to do with the IOS version) and don't see anything indicating that the IOS doesn't support NetFlow...has anyone else out there had this problem or do I need to upgrade to have the ability to configure NetFlow on each interface? Thank you so much for your help!

Cheers,

Travis

The 7600 is not your typical router. It's more closely related to a 6500 than a router. They actually even share some blades.

I think like a 6500 it has a RP and an SP and netflow working in hardware on different levels.

Long story short look at the post for enabling it on a 6500 either here or cisco.

I would also recommend looking at the aging commands for netflow so your TCAM does not overflow. It can cause problems with other things like WCCP that share the same space.

Did you do a "no switchport" first? I don't think those commands work on switchports, need to be router ports.

Travis,

Have you tried 12.4 IOS yet?

srossen

7600 does not run 12.4.

I knew it would be an Arsenal fan to post up the solution! :-) First, let me thank everyone who responded! Your support is GREATLY appreciated and this is what makes the Internet so great...people helping people! I went ahead and tested on a port on the same 7606 Router which was NOT in use and did the following:

router(config)#int gi2/14

router(config-if)#no shut

router(config-if)#ip ?

My only question then would be, is it not possible on a 7606 to get NetFlow going then if the port is a switchport and not a L3 port? It looks like the answer is yes, but wondering if there is a workaround or if this is correct?

That is it!!! Again, thank you so much for the assistance!!! And let's hope Man U gets beat at City and Chelsea slip up at Anfield...GO GUNNERS!!! :-)
