match ip precedence
This command adds to the specified class definition a match condition based on the
value of the IP Precedence field in a packet, which is defined as the high-order three
bits of the Service Type octet in the IP header (the low-order five bits are not checked).
The precedence value is an integer from 0 to 7.
NOTE: The IP DSCP, IP Precedence, and IP ToS match conditions are alter-
native ways to specify a match criterion for the same Service Type
field in the IP header, but with a slightly different user notation.

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
is a two-digit hexadecimal
number from 00 to ff. The value of
is a two-digit hexadecimal number from
00 to ff. The
denotes the bit positions in
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
value of a0 (hex) and a
of a2 (hex).
NOTE: The IP DSCP, IP Precedence, and IP ToS match conditions are alter-
native ways to specify a match criterion for the same Service Type
field in the IP header, but with a slightly different user notation.
NOTE: This “free form” version of the IP DSCP/Precedence/TOS match spec-
ification gives the user complete control when 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
. A value of
ip
matches all protocol number values.
