Parameters
carl-index: Specifies a CAR list by its number in the range of 1 to 199.
precedence precedence: Specifies a precedence value in the range of 0 to 7.
mac mac-address: Specifies a MAC address in hexadecimal format.
mpls-exp mpls-exp-value: Specifies an MPLS EXP value in the range of 0 to 7.
dscp dscp-list: Specifies a list of DSCP values. A DSCP value is in the range of 0 to 63, or any of the
following keywords af1 1, af12, af13, af21, af22, af23, af31, af32, af33, af41, af42, af43, cs1, cs2, cs3,
cs4, cs5, cs6, cs7, default, or ef.
destination-ip-address: Configures a destination IP address-based CAR list.
source-ip-address: Configures a source IP address-based CAR list.
subnet ip-address mask-length: Specifies a subnet by the IP subnet address and IP subnet address mask
length. The range for mask-length is 17 to 31.
range start-ip-address to end-ip-address: Specifies an IP address range by the start address and end
address. end-ip-address must be greater than start-ip-address. The maximum number of IP addresses that
an IP address range can accommodate is 32000.
per-address: Performs per-IP address rate limiting within the network segment. If this keyword is not
specified, rate limiting is performed for the entire network segment.
shared-bandwidth: Specifies that traffic of all IP addresses within the network segment shares the
remaining bandwidth.
Usage guidelines
You can create a CAR list based on IP precedence, MAC address, MPLS EXP, DSCP, or IP network
segment.
You can create multiple CAR lists or modify the parameters for a CAR list.
You can configure up to eight precedence values for a CAR list. If the same precedence value is specified
multiple times, the system considers them as one value by default. If a packet matches a precedence
value on the CAR list, it matches the CAR list.
You can configure up to eight MPLS EXP values for a CAR list. If you specify an MPLS EXP value multiple
times, the system counts them as one value by default. If a packet matches an MPLS EXP value on the CAR
list, it matches the CAR list.
You can configure up to eight DSCP values for a CAR list. If a DSCP value is specified multiple times, the
system counts them as one value by default. If a packet matches a DSCP value on the CAR list, it matches
the CAR list.
