[exclude]

config diffserv class match ipdscp

This command adds to the specified class definition a match condition based on the value of the IP DiffServ Code Point (DSCP) field in a packet, which 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). The <classname> is the name of an existing DiffServ class. The optional [exclude] parameter has the effect of negating this match condition for the class (i.e., match all IP DSCP values except for what is specified here).

The <dscpval> value is specified as either an integer from 0 to 63, or symbolically through one of the following keywords: af11, af12, af13, af21, af22, af23, af31, af32, af33, af41,

af42, af43, be, cs0, cs1, cs2, cs3, cs4, cs5, cs6, cs7, ef.

Note: The ipdscp, ipprecedence, and iptos 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.

Note: To specify a match on all DSCP values, use the config diffserv class match iptos command with <tosbits> set to 0 and <tosmask> set to 03 (hex).

config diffserv class match ipprecedence

This command adds to the specified class definition a match condition based on the value of the IP Precedence field in a packet, which is defined as the high-order three bits of the Service Type octet in the IP header (the low-order five bits are not checked). The <classname> is the name of an existing DiffServ class. The precedence value is an integer from 0 to 7. The optional [exclude] parameter has the effect of negating this match condition for the class (i.e., match all IP Precedence values except for what is specified here).
