To specify a match on all Precedence values, use the match [not] ip tos <tosbits> <tosmask>
Note
:
command with <tosbits> set to 0 and <tosmask> set to 1F (hex).

9.4.10 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).
The ip dscp, ip precedence, and ip tos match conditions are alternative ways to specify a
Note
:
match criterion for the same Service Type field in the IP header, but with a slightly different user notation.
In essence, this the "free form" version of the IP DSCP/Precedence/TOS match specification
Note
:
in that the user has complete control of specifying which bits of the IP Service Type field are checked.

9.4.11 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.
The optional [not] parameter has the effect of negating this match condition for the class (i.e., match all
IP Protocol numbers except for the one specified here).
