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.
Syntax
match dstl4port {portkey | 0-65535} [0-65535]
To specify the match condition as a single keyword, the value for portkey is one of the supported port
name keywords. The currently supported portkey 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.

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).
Syntax
match ip dscp dscpval
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, as described in mark ip-dscp on page 350
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.
