Quality of Service (QoS) Commands
5-16
v1.0, July 2009
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.
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.
