match ip dscp
Use the match ip dscp command in Class-Map Configuration mode to add to
the specified class definition a match condition based on the value of the IP
DiffServ Code Point (DSCP) field in a packet. This field is defined as the
high-order six bits of the Service Type octet in the IP header. The low-order
two bits are not checked.

User Guidelines
The ip dscp, ip precedence, and ip tos match conditions are alternative ways
to specify a match criterion for the same Service Type field in the IP header
but with a slightly different user notation.
To specify a match on all DSCP values, use the match ip tos
command with tosbits set to "0" (zero) and tosmask set to hex "03."
Example
The following example displays how to add a match condition based on the
DSCP field.
