Hi Bimal,
Ethereal cannot capture native Fibre Channel traffic.
However, there may be other options.
If you're using Cisco's SAN equipment, including their MDS series, you
can use their fctrace or fibre channel SPAN (or RSPAN) features to
generate captures that Ethereal can understand. There was a limitation
in earlier codes that I'm not sure was lifted in their 2.0 code, where
the saved FC frame (plus the faux header that gets slapped on the
front) could not be larger than the size of a regular Ethernet frame,
1514 bytes, so it's very possible that the last 500 bytes or so of a FC
frame would get dropped.
I thought at one point I'd found some device that would actually take
FC traffic and encapsulate it in Ethernet, spitting it out another
port, in a way that Ethereal could read (and that any Ethernet packet
capture device could record). Seems to me that it was around $1000,
though I'm having troubles finding any information at all. Let me see
what I can dig up...

Hi All
Are there plans for feature to capture FC/HBA Traffic through
ethereal? Can it be done right now w/ ethereal? If not, what other
options one has to capture info from server side for FC traffic w/o
buying expensive Fabric Analyzer?

Bimal
