This read-only value forms part of the local end-point address for this connection, together with cesLocalVci and cesLocalNSAP, but per the description it is always assigned the value 0 by the switch's Session Manager rather than being independently configurable. An administrator inspecting this connection's local addressing would see 0 here by design, with the meaningful local addressing information instead found in cesLocalNSAP. Because it is fixed at 0, its value carries no diagnostic significance on its own beyond confirming the object behaves as documented.
