VLAN-ACL Configuration Commands

Use the command to perform flow limit on the packets matching the specified
ACL (only available to the rules whose action is permit in the ACL).
ACL (only available to the rules whose action is permit in the ACL).
When the parameter is set, it is required that cir<=pir,cbs<=ebs. It is
recommended to set the values of cbs and ebs 100-150 times of the value of cir.

The setting of tc-index is subject to the following limitations:

remark-cos and remark-policed-service cannot be set at the same time for
the same data flow, neither can remark-drop-priority and
remark-policed-service.

You need to configure the "DSCP+Conform-level І Service parameter"
mapping table before configuring the remark-policed-service action; you
need to configure the "Local-precedence + Conform-level І 802.1p priority"
mapping table before configuring the remark-cos action. Refer to the qos
control-level, dscp, local-precedence command for the descriptions of the
two mapping tables.

Example
# Perform flow limit on packets received on the ports in VLAN 2 if they match the
permit rule in ACL3000. Set the CIR to 2000 kbps, the CBS to 2000 bytes and the
EBS to 2500 bytes. Drop packets when this threshold is exceeded.

Parameter
inbound: Sets priority for packets received on the port.
ip-group { acl-number | acl-name }: Activates the ACL identified by the
acl-number or acl-name argument. The ACL here can be a basic ACL or an
advanced ACL. acl-number: Sequence number of the ACL, ranging from 2000 to
3999. acl-name: Name of the ACL, a string beginning with character a-z or A-Z.
Note that this argument cannot contain spaces.

argument ranges from 0 to 127. Without this keyword, this command applies to
all rules of the ACL.
