Port Mapping

The DSL device provides multiple interface groups. Up to five interface groups are

supported including one default group. The LAN and WAN interfaces could be included.

Traffic coming from one interface of a group can only be flowed to the interfaces in the same

interface group. Thus, the DSL device can isolate traffic from group to group for some

application. By default, all the interfaces (LAN and WAN) belong to the default group, and

the other four groups are all empty. It is possible to assign any interface to any group but

only one group.

IP QoS

The DSL device provides a control mechanism that can provide different priority to different

users or data flows. The QoS is enforced by the QoS rules in the QoS table. A QoS rule

contains two configuration blocks:

Traffic Classification

and

Action

. The

Traffic

Classification

enables you to classify packets on the basis of various fields in the packet and

perhaps the physical ingress port. The

Action

enables you to assign the strictly priority level

for and mark some fields in the packet that matches the Traffic Classification rule. You can

configure any or all field as needed in these two QoS blocks for a QoS rule.
