4.16. [tos] command
TOS/DiffServ (DS) priority function can discriminate the Differentiated Service Code Point
(DSCP) of the DS field in the IP packet header, and map each Code Point to a
corresponding egress traffic priority. As per the definition in RFC2474, the DS field is
Type-of-Service (TOS) octet in IPv4. The recommended DiffServ Code Point is defined in
RFC2597 to classify the traffic into different service classes. The mapping of Code Point
value of DS-field to egress traffic priorities is shown as follows.
