[SunHELP] Re: Network/packet/bandwidth analyzers

[Mike]

I am almost certain that switches filter out any type of packet not
directed to a certain host. This is one of the great benefits over a
hub. I am not certain, but I was a network admin for a couple years and I
know we came across a problem using samba.

Regards,

Mike
