So is the Ethernet port of the MDS 9000 Port Analyzer Adapter:

	directly plugged into an Ethernet port on the machine running Ethereal?

	plugged into a hub into which an Ethernet port on the machine running  
Ethereal is also plugged?

	plugged into a switch into which an Ethernet port on the machine  
running Ethereal is also plugged?

NOTE: not everything called a "hub" is a hub; some are switches.  See

That's for display filters, which don't affect what traffic you capture.

A *display* filter for Fibre Channel traffic would be "fc", not "FC".

A *capture* filter for it would either be

	ether proto 0xfcfc

or

	ether proto 0

assuming that the encapsulation dissected by the "MDS Header"  
dissector is the one used by the Port Analyzer Adapter.
