We have a Fasthub 400 series (WS-C412) hub (refurbished I think). One of our application broadcasts some data that's supposed to appear on a monitor on another PC. It doesn't. It makes us think that WS-C412 is suppressing broadcasts. We do a ping from one of the PCs (there are 4 PCs and 5 LANs. All HUBs are WS-C412) and watch the lights on the HUB and it doesn't look like the PING is broadcast at all (although we don't care about the PING, we do care about HUB suppressing broadcast messages because we need broadcasting capability in other applications). We have a 3COM HUB in another setup and there are no such problems there.
I was wondering if there is some configuration that would allow us to enable broadcasting. I would appreciate anyone's assistance.
