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
alternative 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 <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 <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: This “free form” version of the IP DSCP/Precedence/TOS match
specification gives the user complete control when specifying which
bits of the IP Service Type field are checked.
