way of combination is described in
Note:
Only type-A LPUs support the configurations above.
Only the permit rules in ACLs can be properly applied to the hardware.

1.10.3 Configuration Example

A switch is connected to 10.1.1.1/24 network segment through its Ethernet 2/0/1
port.
Perform RED queue scheduling for all the traffic from the network segment
10.1.1.1/24.
Set the parameters as follows: the packets are dropped at random when the
queue length exceeds 64 Kbytes, all packets are dropped when the queue length
exceeds 128 Kbytes, and the drop probability is 20%.
Configuration procedure:
<H3C> system-view
[H3C] acl number 2000
[H3C-acl-basic-2000] rule permit source 10.1.1.1 0.0.0.255
