Is there a way to create an acl to log broadcast traffic? I'm trying to determine if broadcasts are coming into my router from other sites. (Yes, I know that broadcasts aren't supposed to be forwarded from a router.) I'm seeing IPX SAP broadcasts and I have to figure out where they're coming from. I have DLSw configured at every location, and I'm wondering if, for some reason, it's forwarding this broadcast traffic. Any ideas?

To log broadcast traffic you could try something like this:

access-list 199 permit ip any host log-input

access-list 199 permit ip any any

This will allow all traffic and will log any IP broadcast traffic. But if the broadcasts you are looking for are IPX then it will not do so much good.
