Introduction
Layer 2 adoption A radio port is adopted by a Module in the same Layer 2 domain (subnet).
Software version WS.01.xx only supports Layer 2 adoption; software
version WS.02.xx supports both Layer 2 and Layer 3 adoption.
Layer 3 adoption A radio port is adopted by a Module in another Layer 2 domain (subnet),
separated from the radio port by a router or routing switch. Note: Layer
3 adoption requires the radio port to be running an updated bootloader
code, which is installed automatically when the radio port is adopted at
Layer 2 by a Module running WS.02.xx software.
Radio Port (RP) ProCurve Radio Ports support the 802.1X protocol for port-based access
control as well as LLDP, in the transmit-only mode of operation. Radio
ports receive their configuration and operating information when
adopted by a Wireless EDGE Services xl Module or a Redundant Wireless
Services xl Module.
• When using software version WS.01.xx, a Layer 2, IEEE 802.3af-
compliant device with no IP address and no user interface. A radio
port operates as a Layer 2, IEEE 802.3af-compliant device, using Link
Layer Discovery Protocol (LLDP) and ‘Hello’ messages to announce
its presence to any available Module in the Layer 2 domain (subnet).
If an available Module has sufficient licenses, the radio port is
adopted. This is termed a Layer 2 adoption and it is the only type of
adoption supported using WS.01.xx.
• When using software version WS.02xx, when a radio port is first
powered up in a network, it initially operates as a Layer 2, IEEE 802.3af-
compliant device, as described above. If an available Module has
sufficient licenses, a Layer 2 adoption occurs.
If no Module replies at Layer 2, a radio port then initiates a Layer 3
adoption, which requires an IP address for the radio port and an IP
address of an available Module. When these are supplied, using
DHCP, a Layer 3 adoption of the radio ports occurs. A Layer 3 adopted
radio port has an IP address, but no user interface.
For more information, see “Radio Port Adoption” in the Management and
Configuration Guide for the ProCurve Wireless Edge Services xl Module
and ProCurve Redundant Wireless Services xl Module.
Radio Port VLAN
(Layer 2 Adoption)
A VLAN that carries wireless traffic as well as management, control, and
status information sent between the Module and radio ports. This VLAN
may span multiple switches. This VLAN includes the Module's downlink
port (<slot-id>DP), configured with tagged VLAN membership, the switch
port to which the radio port is directly attached as an untagged member,
and other ports connecting infrastructure switches (when applicable)
tagged or untagged, according to the network topology.
The Auto-VLAN is an automatically created and configured radio port
VLAN used for Layer 2 adoption. While there can be multiple radio port
VLANs, there is only one radio port Auto-VLAN.
