Which Cisco NX-OS command displays the VSAN that is associated with each FCID?

• Dshow flogi database

Explanation

show fcdomain (option A) is correct because the FcDomain process in NX-OS manages Fibre Channel domain IDs and FCID assignments - running this command displays FCID-to-VSAN mappings, domain IDs, and principal switch information per VSAN.

Why the distractors are wrong:

• B. show fc2 plogi - FC2 is a Fibre Channel protocol layer command unrelated to FCID/VSAN mapping; it doesn't exist as a standard NX-OS display command in this context.
• C. show vsan database - This shows which interfaces/ports belong to which VSAN, not FCID assignments.
• D. show flogi database - FLOGI (Fabric Login) shows end-device logins (WWN-to-FCID mapping), but does not display the VSAN-to-FCID association in the same structured way; it's focused on logged-in N-ports, not domain-level FCID allocation.

Memory tip: Think "FcDomain = FC address domain" - since FCIDs are domain-based addresses (Domain.Area.Port), show fcdomain is the natural command to see how FCIDs map across VSANs.
