A state university storage engineer needs the actual Fibre Channel frames from one MDS port to inspect a malformed host sequence. Which tool collects those frames?
Select an answer to reveal the explanation.
Short Explanation
You need the frames themselves, not a rumor about them. A SPAN session copies that MDS port to an analyzer on an SD port, which is how you see a malformed sequence. Aliases, zones, and domain elections do not store the frames.
Full Explanation
MDS SPAN copies Fibre Channel frames from a source interface, or from a VSAN, to a SPAN destination port. An analyzer attached to that SD port sees the actual frames, which is the only way in this list to inspect a malformed sequence on the university port. A device alias is a fabric-wide name for a WWPN. Committing the alias database distributes names, and it does not retain the frames those devices sent. Zoneset activation updates the zoning enforcement plane. The active zoneset is a list of members, not a packet capture. Changing domain-manager priority may affect which switch is principal the next time the domain elects one. It does not replay frames that already crossed a port. Caveat: the destination port has to be a real SD port with an analyzer that understands Fibre Channel, and SPAN shows what you sourced, not an entire fabric, unless that is the source you chose. Operational check: configure the SPAN source as the port in question, confirm frames arrive on the SD port, and capture while the host repeats the failing sequence.
