QoS Commands
1-25
 Note:
LPUs that are not A-type support applying the combination of IP ACL rules and link
ACL rules. However, the field defined by the IP ACL rules and link ACL rules cannot be
of more than 32 characters. Otherwise, the combination cannot be applied
successfully.

Parameters
inbound: Performs traffic policing on the packets received by the port.
outbound: Performs traffic policing on the packets sent by the port.
acl-rule: Applied ACL which can be the combination of various ACL rules. For the ways
of type-A LPUs to combine ACLs and the description on related parameters, refer to
Table 1-4 and Table 1-6. For the ways of non-type-A LPUs to combine ACLs and the
description on related parameters, refer to
Table 1-5 and Table 1-6.
system-index: Specifies an interior index value which is used when an ACL rule is
applied to the port. The index value ranges from 0 to 4,294,967,295. This keyword is
only available when the ACL rule number is specified in the command. After the
specified ACL takes effect, there are three scenarios when you input the index value:
z If you do not input an index value or the index value you input is 0, the system will
automatically assign an index whose value is greater than 0;
z If the input index value is not 0 and does not conflict with the interior index used by
the system, the system will adopt the index value input by you;
z If the input index value is not 0 but conflicts with the interior index used by the
system, the system will reassign an index value.
When the specified ACL rule is not effective, the system will adopt the index value input
by you.
kbps: Specifies the limit rate to be measured in kbps. If the kbps keyword is specified,
the rate is measured in kbps, in the range of 64 to 1,024,000 with the granularity being
64. If the number you input is in the range of N*64 to (N+1)*64 (N is a natural number),
the switch will set the value to (N+1)*64 kbps automatically.
target-rate: Total rate to limit all the packets sent on a port. For type-A LPUs, the
target-rate argument is in the range of 64 to 8,388,608 in kbps with the granularity being
64. If the kbps keyword is not provided, the target-rate argument is expressed in mbps
in the range of 1 to 1,000.
exceed action: Optional. The action is taken when the traffic exceeds the threshold.
Only type-A LPUs support this keyword. The action argument can be:
