Apparatus, and an associated method, for facilitating exchange of configuration indicia associated with a mobile node operable in a radio communication system. The mobile node is dynamically-configurable, and includes a DevMan tree. The indicia is provided to a network manager responsive to request therefore or upon initiation by the mobile node. When initiated at the network, a request message generator located at a network manager generates a Get message to request a root directory of the be provided to the network manager. The mobile node, upon delivery of the Get message thereto, retrieves an object map of the DevMan tree, defines it using recursion in a single response message, and sends the object map to the network manager.
