Parameter
enable
: Enable the inbound CAR function.
disable
: Disable the inbound CAR function.
Description
Use the
inboundcar enable
command to enable the inbound CAR function.
Use the
inboundcar disable
command to disable the inbound CAR function.
By default, the inbound car is disabled.
Note:
The
inboundcar
command is only effective to the type A card.
The
inboundcar
command takes effect only after you restart the switch.
When the inbound CAR function is enabled and the same ACL rules are sent to the
different ports, they are treated as different rules, thus seizing multiple entries. If you
configure the CAR function for the traffic matching the same rule on multiple ports, the
switch provides a bandwidth gurantee to the traffic matching the CAR rule on each port.
When the inbound CAR function is disabled and the same ACL rules are sent to the
different ports, they are treated as the same one, thus seizing one entry only. If you
configure the CAR function for the traffic matching the same rule on multiple ports, the
switch provides a bandwidth gurantee to the traffic matching the CAR rule on these
ports.
For example, to set the CAR bandwidth of 2 M for the traffic matching the rule 0 on the
switch, use the
traffic-limit
command to configure the CAR rule on two ports. The
following describes the bandwidth gurarantee with inbound CAR function enabled or
disabled.
