acl-rule: Applied ACL rules which can be the combination of various ACL rules.
Type-A I/O Modules’ way of combination is described in
Table 496, and
non-type-A I/O Modules’ way of combination is described in Table 497.
n
■ Only type-A I/O Modules support the configuration above.
■ Only the rules with the permit action can be properly applied to the hardware.
Configuration Example ■ Ethernet1/0/1 of the switch is accessed into the network segment 10.1.1.1/24.
■ Enable the function of assured bandwidth for traffic from the network
segment 10.1.1.1/24.
■ Set the parameters as follows: the minimum assured bandwidth is 64 kbps, the
maximum available bandwidth is 128 kbps, and the weight of bandwidth is 50.

Configuring
Traffic-Based Flexible
QinQ
QinQ is to encapsulate the VLAN tags of the private network in the VLAN tags of
the public network in order that the packets are transmitted through the
backbone network of the carrier (also called public network). The traffic-based
flexible QinQ function can tag a packet with external VLAN tags according to the
ACL rule that the packets matches on the inbound port.
The traffic-based flexible QinQ function is configured on the hybrid port of the
edge device connecting the user device to the carrier’s network.
