This OID returns the Relative Name (RN) of an FC (Fibre Channel) zoning endpoint — one end of a zoned FC connection between a host or storage port and the fabric, given as a SnmpAdminString — the naming fragment that distinguishes this instance from its sibling FcEndpoint objects under the same parent in UCSM's object tree. Admins use the RN, combined with the parent's DN, to reconstruct exactly where this FcEndpoint instance sits in the hierarchy without needing the full DN string on its own. For example, if two FcEndpoint instances exist under the same parent object, their RNs are what differentiate row one from row two when UCSM lists both under that parent.
