Quick Question,

Connected a DS-PAA-2 to the IP and FC network. SPAN is configured.
After lunching ethereal, we see the TCP/IP packets only, no FC packets.

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

	http://wiki.wireshark.org/HubReference


Click the Filter, not even find FC as an option.

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.
