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 monitoring session's source port. For this FC monitoring session's source port, 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 the physical FC port whose traffic is being mirrored/copied 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 37, rather than a full path.
