match ip tos

This command adds to the specified class definition a match condition based on the value of the IP

TOS field in a packet, which is defined as all eight bits of the Service Type octet in the IP header.

The value of <

tosbits> is a two-digit hexadecimal number from 00 to ff. The value of <tosmask> is a

two-digit hexadecimal number from 00 to ff. 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). The <

tosmask> denotes the bit positions in <tosbits> that are used for comparison

against the IP TOS field in a packet. For example, to check for an IP TOS value having bits 7 and

5 set and bit 1 clear, where bit 7 is most significant, use a <

tosbits> value of a0 (hex) and a

tosmask> of a2 (hex).

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: In essence, this the “free form” version of the IP DSCP/Precedence/TOS match

specification in that the user has complete control of specifying which bits of the IP Service Type

field are checked.

Default

None

Format match [not] ip tos <tosbits> <tosmask>

Mode Class-Map Config

match protocol

This command adds to the specified class definition a match condition based on the value of the IP

Protocol field in a packet using a single keyword notation or a numeric value notation.

To specify the match condition using a single keyword notation, the value for <

protocol-name> is

one of the supported protocol name keywords. The currently supported values are:

icmp, igmp, ip,

tcp, udp

. Note that a value of ip is interpreted to match all protocol number values.

To specify the match condition using a numeric value notation, the protocol number is a standard

value assigned by IANA and is interpreted as an integer from 0 to 255.

Note: This command does not validate the protocol number value against the current list defined

by IANA.
