How do I set DiffServ Code Points (DSCP) a media-policy?

The media-policy configuration element allows the SD to set the TOS bits for various types of traffic.  Most customers do not use the outdated TOS value, but rather specify a DSCP value they would like to use.  Since the DSCP value is only 6 bits long and the TOS value is 8 bits long this creates some rather odd conversions. 

 

 

To convert from a DSCP value to a TOS value you must take the DSCP value in binary, add two 0's in the least significant bits and then change this value to hexadecimal.  To make things simple you can use the table below.  Basically find the DSCP value you desire on one of the first 4 columns and use the "TOS Value" in the 5th column in your media-policy.
