7.21.2.13 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 i nteger from 0 to 7.
Syntax
match ip precedence <0-7>
i
The ip dscp, ip precedence, and ip tos match conditions are alternative ways to specify a
match criterion for the same Service Typ e field in the IP heade r, but with a slightly different
user notation.
To specify a match on all Precedence values, use the match [not] ip tos <to sbits>
<tosmask> command with <tosbits> set to 0 and <tosmask> set to 1F (hex).

7.21.2.14 match ip tos

This command adds to the spe cified cla ss definition a match con dition based on t he value of th e IP TOS
field in a packet, which is defined as all eight bits of the Service Type octet in the IP header.
Syntax
match ip tos <tosbit s> <tosmask>
<tosbits> is a two-digit hexadecimal number from 00 to ff.
<tosmask> is a two-digit hexadecimal number from 00 to ff.

The <tosmask> denotes the bit positions in <tosbits> that are used for co mparison against the

IP T OS field in a p acket. For example, to check for an IP T OS value having bit s 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).
