             If implemented as read-create in the Cable Modem
             Termination System, creation of entries in this table is
             controlled by the value of docsIfCmtsQosProfilePermissions.

             If implemented as read-only, entries are created based
             on information in REG-REQ MAC messages received from
             Cable Modems (Cable Modem Termination System
             implementation), or based on information extracted from
             the TFTP option file (Cable Modem implementation).
             In the Cable Modem Termination system, read-only entries
             are removed if no longer referenced by
             docsIfCmtsServiceTable.

             An entry in this table must not be removed while it is
             referenced by an entry in docsIfCmServiceTable (Cable Modem)
             or docsIfCmtsServiceTable (Cable Modem Termination System).

             An entry in this table should not be changeable while
             it is referenced by an entry in docsIfCmtsServiceTable.

             If this table is created automatically, there should only
             be a single entry for each Class of Service. Multiple
             entries with the same Class of Service parameters are not
