Managed Switch CLI Manual, Release 8.0.3
Quality of Service (QoS) Commands 8-16
v1.0, July 2010
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).

specify a match criterion for the same Service Type field in the IP header, but with
a slightly different user notation.
