Developers Guide for more information on programming a bond interface using the CPS API.
VLAN interfaces
Virtual LANs (VLANs) dene broadcast domains in a Layer 2 network, and an NPU VLAN entity is modeled as a separate Linux bridge
instance.
NPU entities (VLANs) are mapped to Linux entities (bridges). An NPU VLAN entity uses the MAC address from the rst port added as its
member port. The bridge interface is operationally up when at least one of its member interfaces is up. You can assign IP addresses to
multiple bridge interfaces to create an inter-VLAN routing domain.
