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.

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.
