See

	http://www.ethereal.com/faq#q5.1

for more information.  (It doesn't mention Avaya switches because, at
the time, I didn't even know Avaya *made* LAN switches.  If somebody can
supply a link to Avaya documentation on doing port mirroring - or
documentation for any *other* LAN switches not mentioned there - please
do so, so that we can update the FAQ.)
