Any Cisco experts out there!

Does anyone know the sequence of commands to use to monitor the ip traffic that is being sent down a particular port on a Cisco 6509?

I need to see what IP's are sending traffic, and how much traffic, to the host that is on the end of my GigabitEthernet9/11 port?

Any ideas?

Alfie,

I would download a sniffer like http://www.ethereal.com/ and use that, it works really well and is free :bannana: I have used it to find all sorts of problems

No Cisco Expert but have just "borrowed" these links from the E-E site:

See Network Data Analyzer

Here's more than I could ever tell you about NetFlow:

For your Cat 6509, you might want to look at the NetFlow card:

Thanks, I have this already.

I need to actually see whats going down a particular port on the Cisco 6509 and most importantly where its coming from. I know there is a way of doing this on the switch itself, but finding it is becoming a nightmare.

Scratch that - just re-read your post.

Netflow/Rmon is most likely worth a look.

It depends if you're running CatOS or IOS:

CatOS:

set span <src_port> <dst_port>

IOS:

monitor session 1 source <interface>
monitor session 1 dest <interface>

Hope this helps,

Andy.
