Port Binding
11.1 Overview
Port binding aggregates port connections into logical groups. Bind WAN virtual channels (VCs) to
Ethernet ports and WLANs to specify how traffic is forwarded. The Device forwards traffic from an
Ethernet port only through the bound WAN virtual channel and vice versa. For ports not belonging
to a port binding group, the Device forwards traffic according to the routing table.
Additionally, specify ATM QoS setting
s for an ADSL virtual channel (PVC) to satisfy the bandwidth
requirements of the traffic the PVC carries. For example, create two port binding groups on the
device (R1) for two different WAN ATM PVC connections. The first PVC (PVC1) handles non time-
sensitive data traffic. The second PVC (PVC2) handle time sensitive Media-On-Demand (MOD) video
traffic.
