Note:
Combined activating of IP ACL and Link ACL is supported by the Cards except A Type
Ones. But the sum of the bytes number defined by IP ACL and that defined by the Link
ACL can not exceed 32 bytes; otherwise the ACL can not be activated.
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.
If the inbound CAR function enabled, the two ports provides 2M bandwidth
gurarantee for the traffic mathching the rule 0 on each port.
If the inbound CAR function enabled, the two ports provides the total bandwidth
gurarantee of 2M for the traffic mathching the rule 0 on the two ports.
You should first define an ACL before this configuration task.
This configuration achieves rate control for those packets match the ACL. If the traffic
rate threshold is exceeded, corresponding measures will be taken, for example,
dropping excessive packets.
