RE: Re: FAQ 10/100 Hubs Block Other Speed Traffic

Also:  Can we add a list of hubs that are known to have this 
feature?  Or that
_don't_ have it?  I know what I have works dandy, but I'm out 
of town and
can't check the model number.

The bad thing about hubs that _don't_ have this "feature", is that
in order to support 10bt devices, they throttle the entire hub speed
down to 10bt if there is one or more 10bt only devices hooked up to it.
I have seen this behavior (and did the bandwidth tests to proove it) on
old 3com office connect 10/100 hubs (newer ones do the 2 hubs with a switch
thing.)  So, the point of what I am saying is, since these old hubs have
no switching capabilities, and they don't know which port the traffic is
supposed to go to (no switch=no arp table), they have to throttle bandwidth.
If you have one 10bt device on these, you basically have a 10bt hub.  Save
your
money and just buy a 10bt hub.
