This SnmpAdminString holds the Relative Name (RN) — the final path segment that, appended to the parent's DN, produces the full DN of this FC monitor source reference. For this FC monitor source reference, the RN is generated from the object's own key properties (such as an ID, port number, or session number) so that every instance of a linking record identifying exactly which object (port, VSAN, or endpoint) is supplying the mirrored traffic for an FC monitoring session gets a distinct, non-colliding suffix under its parent container. A typical RN value here looks like a short hyphenated token, for instance one incorporating the number 10, rather than a full path.
