To specify the match condition using a numeric notation, one layer 4 port number is required. The port
number is an integer from 0 to 65535.
To specify the match condition using a numeric range notation, two layer 4 port numbers are required and
together they specify a contiguous port range. Each port number is an integer from 0 to 65535, but with
the added requirement that the second number be equal to or greater than the first.
The optional [not] parameter has the effect of negating this match condition for the class (i.e., match all
destination layer 4 port numbers except for the one specified here).

8.4.8 match ip dscp
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 optional [not] 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 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.
Note
:
To specify a match on all DSCP values, use the match [not] ip tos <tosbits> <tosmask>
command with <tosbits> set to 0 and <tosmask> set to 03 (hex).

8.4.9 match ip precedence
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 precedence value is an integer from 0 to 7. The
optional [not] 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).
Note
:
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.
