This object is the local SCTP port number used by this specific association. Because the range here reflects a dynamic ephemeral port assignment, matching this port against known SIGTRAN service ports, such as 2905 for M3UA, tells the admin whether this device initiated the connection from a dynamic port or is listening on a well-known one. A local port of 2905 would indicate this side is acting as the M3UA listener, while a high dynamic port such as 21341 suggests this device initiated the connection outward.
