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.
1. High priority with DS-field.
Expected Forwarding (EF)
Assured Forwarding (AF)
2. Low Priority with DS-field:
Assured Forwarding (AF)
1. -print : display all current configurations.
2. –rtptype: set DSCP value of signaling packets from 0 to 63
3. –siptype: set DSCP value of RTP packets from 0 to 63
?
This command won't be functional until whole network environment support DSCP function,
Note: e.g. all routers or switches in your network have enabled DSCP feature.
