I've got an 2824 Procurve switch broadcasting a lot.
Any suggestion about best practice on setup for the switch ?

How do you know it's a lot? What have you done to test it and measure it?

Is Spanning-Tree enabled?

I don't recall if the 2824 used the GUI type interface or the CLI.
If it uses the CLI , can you post the output of show run , and if it has the command in the IOS show counters or show interface counters (can't remember the exact syntax).
You should only be getting broadcasts on a switched network if you have information specificly destined for or multicast traffic. You shouldn't have much multicast going on unless you have something on the network streaming music or PTP networks going on. You could have a NIC chattering. If you have a loop in your cabling, you could have a broadcast storm going on.

Your fault finder sensitivity is set to high.. It will pretty much always say excessive broadcast with that setting.
try dropping it to medium and see what happens.

Hold the question until that.
