<tosmask> is a two-digit hexadecimal number from 00 to ff.
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
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 in that the user has complete control of specifying which bits of the IP Service
Type field are checked.

7.21.2.15 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.
Syntax
match protocol {<protocol-name> | <0-255>}
<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.
i
This command does not validate the protocol number value against the current list defined
by IANA.
Default Setting
None
