Netflow on older 6500 Sup 2, PFC 2

routerspecialist

So, it's not working. I admit, these are older 6500's. The IOS is: Version 12.1(27b)E4.

Here's the problem: I don't see any detail in the netflow pages on this device other than interface stats, no ports, protocols, etc. in Orion's netflow analyzer. None of the good stuff that I get from other 6500s with Sup 720s. Is it possible that the Sup2, PFC2, can't do netflow?

I have my config below (the global part which relates to netflow). And on the interfaces, trust me, I do ip route-cache flow configured.

Any ideas out there????

The config:

ip flow-export version 5
ip flow-export destination 10.x.x.x 2055

mls flow ip destination
mls nde sender

And some show commands:

DIST#sh mls nde

Issue resolved; flow export source did not match Orion's expected monitoring port

Is there a reason you are using version 7? Can you change that to v5 or v9? Most customers run those versions and I want to make sure there isn't some issues with the old IOS and v7 that we aren't aware of. In general, we will consume flows that contain the fields in this KB.

Can you run a wireshark capture and post some of the data here? You can use the display filter cflow to show the packet flows. Just expand the data portion (white out information you don't want everyone to see) and grab a screen capture.

So, I changed these to version 5, no difference. Still not showing up in NTA. A packet capture will take some time.
