Parameters
enable: Enables the inbound CAR feature.
disable: Disables the inbound CAR feature.
Description
Use the inboundcar enable command to enable the inbound CAR feature.
Use the inboundcar disable command to disable the inbound CAR feature.
By default, the inbound CAR feature is disabled.
 Note:
This command is only applicable to A-type LPUs and can take effect only after you
restart the switch.
When the inbound CAR feature is enabled, the same ACL rule applied to different ports
is treated as different rules, thus seizing multiple entries. If you enable the CAR feature
for the traffic matching the same rule on multiple ports, the switch provides guaranteed
bandwidth to the traffic matching the CAR rule on each port.
When the inbound CAR feature is disabled, the same ACL rule applied to different ports
is treated as the same one, thus seizing one entry only. If you enable the CAR feature
for the traffic matching the same rule on multiple ports, the switch provides guaranteed
bandwidth to the traffic matching the CAR rule on these ports.
For example, if you want to set the CAR bandwidth of 2 M for the traffic matching ACL
rule 0 on the switch, use the traffic-limit command to enable the CAR feature on two
ports.
