9.4.7 match dstl4port

This command adds to the specified class definition a match condition based on the destination layer 4 port of a packet using a

single keyword or numeric notation or a numeric range notation.

To specify the match condition as a single keyword, the value for is one of the supported port name keywords. The

currently supported values are: domain, echo, ftp, ftpdata, http, smtp, snmp, telnet, tftp, www. Each of these

translates into its equivalent port number, which is used as both the start and end of a port range.

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).

Default None

Format

match [not] dstl4port { | <0-65535> [<0-65535>]}

9.4.8 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 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 command with

set to 0 and set to 03 (hex).

Default None

Format

match [not] ip dscp

9.4.9 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).
