342 | Quality of Service (QoS) Commandsw w w . d e l l . c o m | s u p p o r t . d e l l . c o mmatch dstl4portThis command adds to the specified class definition a match condition based on the destination Layer 4port 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 portname 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 isused 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 portnumber is an integer from 0 to 65535.To specify the match condition using a numeric range notation, two Layer 4 port numbers are requiredand together they specify a contiguous port range. Each port number is an integer from 0 to 65535, butwith the added requirement that the second number be equal to or greater than the first.Default noneMode Class Map (The prompt is “(Config-classmap)#”.)match ip dscpThis command adds to the specified class definition a match condition based on the value of the IPDiffServ Code Point (DSCP) field in a packet, which is defined as the high-order six bits of the ServiceType octet in the IP header (the low-order two bits are not checked).Syntax match ip dscp dscpvalThe dscpval value is specified as either an integer from 0 to 63, or symbolically through one of thefollowing 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 350Note: The IP DSCP, IP precedence, and IP TOS match conditions are alternative ways to specify amatch criterion for the same Service Type field in the IP header, but with a slightly different usernotation.Default noneMode Class Map (The prompt is “(Config-classmap)#”.)
