OLICING ONFIGURATION
You can configure several CAR policies by using the command for several times.
And the executing order of the policies depends on the configuration order.
Execute the command in interface view, and the setting is valid on the current
interface only.
# Configure traffic policing for outbound packets that conform to CARL rule 1 at
the interface Ethernet1/0. The normal traffic is 200 kbps. The burst size, twice of
the normal traffic, is allowed at the first time; then packets are normally
transmitted when the rate is less than or equal to 200 kbps. When the rate is
larger than 200 kbps, packets will be transmitted after their precedence is
changed to 0.

Use the
undo qos carl
You can establish a CARL based on IP precedence, or MAC address.
For different carl-index, the repeat execution of this command will create multiple
CARLs, and for the same carl-index, such undertaking will modify the parameters
of the CARL.
You can define eight precedence values at most. If the same precedence is
specified for several times, the system by default regards that only one
precedence value has been specified. The precedence values are related to one
another in the way of "OR".
