5.15 [tos] command

ToS/DiffServ (DS) priority function can discriminate the Differentiated Service Codepoint (DSCP) of the DS field in the IP packet header, and map each Codepoint 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 Codepoint is defined in RFC2597 to classify the traffic into different service classes. The mapping of Codepoint value of DS-field to egress traffic priority is shown as follows.

(2)Assured Forwarding (AF)	001010	====>	10 (Decimal System)
