This OID returns the Relative Name (RN) of an FC traffic-monitoring (SPAN) session configured on a fabric interconnect to mirror Fibre Channel traffic for analysis, given as a SnmpAdminString — the naming fragment that distinguishes this instance from its sibling FcMon 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 FcMon instance sits in the hierarchy without needing the full DN string on its own. For example, if two FcMon instances exist under the same parent object, their RNs are what differentiate row one from row two when UCSM lists both under that parent.
