DOCSIS Qos Param Set Tos And Mask

1.3.6.1.4.1.2011.2.25.127.7.1.2.1.21

IP packets TOS value. The IP packets TOS byte is bitwise ANDed with docsQosParamSetTosAndMask and result is bitwise ORed with docsQosParamSetTosORMask and result is written to IP packet TOS byte. A value of 'FF'H for docsQosParamSetTosAndMask and a value of '00'H for docsQosParamSetTosOrMask means that IP Packet TOS byte is not overwritten. Even though the this object is only enforced by the Cable Modem Termination System (CMTS), Cable Modems must report the value as signaled in the referenced parameter. This combination is reported if the referenced parameter is not present in a QOS Parameter Set.
