I've got a native IOS 6509 running 12.1(20)E2 code that I would like to get netflow from on a layer 2 port.
Poor setup of the network dictates this need but if it can't be done I'll simply have to fix the network I guess (Painful)
Here is the config I have in place:
mls aging fast time 64 threshold 1
mls aging normal 32
mls flow ip interface-full
mls flow ipx destination
mls nde sender
ip flow-export version 5
ip flow-export destination <NDE> <port>
As I said; the port is a layer 2 port and in fact this Native IOS doesn't do any routing at all - just switching. But the port I need is the one that goes to our internet provider, previous Network Gump did this though I'm not quite sure why.
Re: Netflow on a Native IOS 6509 running 12.1(20)E2
OK, the trick here is you need to enable on both the router(MSFC) and the switch supervisor. Because you are running mls on that switch, Netflow needs to see the flow setup which hits the router before it passes the flow to mls. This link describes the config for both.
