This SnmpAdminString holds the Relative Name (RN) — the final path segment that, appended to the parent's DN, produces the full DN of this SAN uplink port. For this SAN uplink 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 one physical FC or FCoE uplink port that is a member of the fabric interconnect's SAN cloud 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 36, rather than a full path.
