Table 3 Configuration items of applying a CAR list to an interface
Item Description
Interface Name
Specify the interface to which a CAR list is to be
applied.
Direction
Specify the direction in which a CAR list is to be
applied.
• Inbound: Applies the CAR list to the packets
received on the specified interface.
• Outbound: Applies the CAR list to the packets sent
out the specified interface.
CAR List Index Specify the index of the CAR list to be applied.
CIR
Set the committed information rate (CIR).
IMPORTANT:
If you apply an IP network segment-based CAR list
to an interface, the CIR you defined takes on
different meanings depending on the configurations
of the per-IP address rate limiting function and the
shared bandwidth mode for the CAR list.
z If the per-IP address rate limiting function is not
enabled, the CIR specifies the total bandwidth for
the network segment and will be allocated to
each IP address based on its traffic size.
z If the per-IP address rate limiting function is
enabled but the shared bandwidth mode is not
enabled, the CIR specifies bandwidth for each IP
address, and the bandwidth cannot be shared by
the other IP addresses in the network segment.
z If both the per-IP address rate limiting function
and the shared bandwidth mode are enabled, the
CIR specifies the total shared bandwidth for the
network segment, which will be dynamically and
evenly allocated to traffic by IP address.
For example, apply a CAR list to an interface with 10
Mbps of total bandwidth to perform per-IP address
rate limiting for the network segment 10.1.0.1 to
10.1.0.100. If the shared bandwidth mode is enabled
for the CAR list, you can set the CIR to 10 Mbps at
maximum; if the shared bandwidth mode is not
enabled for the CAR list, you can set the CIR to 100
kbps at maximum.
CBS
Set the committed burst size (CBS), that is, the size of
burst traffic when the actual average rate is no bigger
than CIR.
EBS Set the excess burst size (EBS)
Green
Set the action to be taken on conforming packets.
• Discard: Drops the packets.
• Pass: Permits the packets to pass through.
Red
Set the action to be taken on excess packets.
• Discard: Drops the packets.
• Pass: Permits the packets to pass through.
