Parameter
inbound: Performs traffic statistic on the packets received by the port.

acl-rule: Applied ACL rules which can be the combination of various ACL rules. For the
ways of combining ACLs and the description on related parameters, refer to

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 4294,967,295. 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.
