Hi friends,

We have a L3 4506 Switch on when we have created a L3 interface which has a dedicated 20mbps link, prior the link was free but now its completely used.

Now we want to know which ip's are using it, who are the top talkers n for that one option was Netflow but 4506 L3 dont support netflow so please tell me what can be done for that.

what is the substitute for netflow, please help.

You could span the port into an appliance and analyze the traffic there using open source tools. (e.g., something like security onion).

Can you get Netflow from the distant end?
