1772 CHAPTER 105: TRAFFIC POLICING (TP) CONFIGURATION COMMANDS

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.

Examples # 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.

Parameters carl-index: CAR list number, in the range 1 to 199.

precedence-value: Precedence, in the range 0 to 7.

mac-address: Hexadecimal MAC address.

dscp-list: DSCP value list. When it is displayed by a number, it ranges from 0 to 63; when it is displayed as a character, it can be valued af11, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cs1, cs2, cs3, cs4, cs5, cs6, cs7, default and ef.

Description Use the qos carl command to establish or modify a CARL.

Use the undo qos carl command to delete a 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”.
