docs Mcast Authorization Cmts Cm Status Max Num Sess

This attribute indicates the CM signaled value in Maximum Multicast Sessions Encoding during the CM registration process. If this value is missing the DefMaxNumSess attribute of the Ctrl object is used to determine the maximum number of multicast sessions this client may forward. The value 0 indicates that no dynamic joins are permitted. The value 65535 (the largest valid value) indicates that the CMTS permits any number of sessions to be joined by clients reached through the CM.
