ToS Rewrite
The following example will rewrite the ToS Precedence and the ToS fields to 5 and 30 if the
incoming packet is from the 10.10.10.0/24 network with the ToS Precedence field set to 2 and the
ToS field set to 7. (In this example, the MBZ bit is included in the ToS field.) The figure below
shows how the parameter values are derived.
The <tos-mask> value determines the ToS bit to be examined, which is all eight bits in this
example. The following command configures the ToS rewrite for the example:
Monitoring QoS
The XP provides display of QoS statistics and configurations contained in the XP.
To display QoS information, enter the following commands in Enable mode:
1
0000
111

Incoming Packet:
<tos> = 71
ToS Precedence = 2 ToS = 7
Mask (look at
<tos-mask> = 255
ToS Precedence = 5 ToS = 30
<tos-precedence-rewrite> = 5
<tos-rewrite> = 30
