X11 Broadcast over network

I have a few network stations (X terminal devices) that connect to a unix server with the X11 protocol. These station seem to eat up tons of bandwidth, broadcasting to every port on the network. We are a fully switched network, yet I can see all the packets to and from these devices on every port. Any ideas?

Re: X11 Broadcast over network

What's the type of your switch? If it's cat4k,cat5k or cat6k,you can enable "Broadcast Suppression" feature.If it's cat35xx or cat29xx,your can enable "Flooding Controls".

Re: X11 Broadcast over network

The end point is a Cat4003 and the core is a 6509. Yes I could enable broacast suppresion, but these packets should not be broadcast and I don;t know why. They have source and destination IP addresses, and are IP based packets. I don't know why I see them on every port.
