Overview
Radio Ports as Layer 3 Devices
When using software version WS.02.xx and later, you can configure the
network to allow radio port adoption and communication over Layer 3.
Note Layer 3 adoption requires an updated bootloader code in a radio port. A radio
port used in a WS.01.xx system first must be adopted at Layer 2 by a Module
running WS.02.xx or later to get the required bootloader code update that
allows Layer 3 adoption.
A radio port initially attempts to establish communication with a Module using
Layer 2. If that fails, a radio port sends a DHCP request to begin the process
of establishing communication with a Module. Once the radio port is assigned
an IP address and a default gateway, the radio port next needs a Module’s IP
address. Depending on your network configuration, a Module’s IP address can
be provided using either a special DHCP option (option 189) or through
Domain Name System (DNS). Figure 2 below shows the VLANs and network
components needed when doing Layer 3 radio port adoption. For more
information, see “Network Requirements for Layer 3 Adoption” in the
ProCurve Wireless Edge Services xl Modules Management and Configura-
tion Guide.
