See

	http://wiki.ethereal.com/CaptureSetup_2fEthernet

for a discussion of this on Ethernet, and

	http://wiki.ethereal.com/CaptureSetup_2fTokenRing

for some similar information for Token Ring.

See

	http://wiki.ethereal.com/SwitchReference

for information about span/mirror/etc. ports on various switch models 
(or pointers to that information) - note that not all switches, 
especially low-end ones, support this - and see

	http://wiki.ethereal.com/HubReference

for information about hubs - note that some "hubs" are actually switches.
