PORT MAPPING

The modem/router provides multiple interface groups and there are up to five supported

groups, 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 of the

same group. Thus, the modem/router 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 one group.

IP QoS

The modem/router provides a control mechanism that can provide different priority to

different users or data flows. The QoS (Quality of Service) is enforced by the QoS rules in

the QoS table. A QoS rule contains two configuration blocks:

Traffic Classification

and

Action

. The Traffic Classification feature enables you to classify packets on the basis of

various fields in the packet and perhaps the physical ingress port. The Action

feature

enables you to assign priority level for 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 single QoS rule.
