Re: promiscuous mode

["Robert D. Currier" <rdc@netcom.duke.edu>]

Um,

You *are* on a -shared- network port, not a switched
port, aren't you?  Doesn't matter whether you promiscous
mode turned on or not if you're on a switched port. You'll
only see traffic destined for that host.

We use optical splitters to peel a portion of the signal
out for monitoring purposes.  Mirror ports work as well, but
they add CPU overhead to the router.
