This OID returns the Relative Name (RN) of an administrative override of that zoning namespace's normal zone-ID allocation limit, given as a SnmpAdminString — the naming fragment that distinguishes this instance from its sibling FabricZoneNsOverride 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 FabricZoneNsOverride instance sits in the hierarchy without needing the full DN string on its own. For example, if two FabricZoneNsOverride instances exist under the same parent object, their RNs are what differentiate row one from row two when UCSM lists both under that parent.
