Radio Ports
Installing a ProCurve Wireless Edge Services zl Module or a ProCurve
Redundant Wireless Services zl Module in a zl switch creates a wireless
services-enabled switch that centrally configures and manages ProCurve
Radio Ports, distributed throughout a network, to provide 802.11 wireless
services.
A Module has no visible external ports. It communicates with the wired
(uplink) and wireless (downlink) sides of the network through the VLAN
connectivity of its internal ports. An Uplink VLAN, containing the Module’s
uplink port, communicates with the wired side of the network; Downlink
Radio Port VLANs, containing the Module’s downlink port, communicate with
the wireless side of the network. The internal Module ports are tagged
members of their respective VLANs.
Note It is recommended that any infrastructure switch connecting a radio port and
the wireless services-enabled zl switch also be a member of a management
VLAN that includes that zl switch. This provides management of these
switches through the wireless services-enabled zl switch.
Licenses
Licenses installed on the Wireless Edge Services zl Module, the primary
Module, determine how many radio ports can be controlled. When shipped
from the factory, the primary Module contains a license for 12 Radio Ports.
Additional licenses can be purchased.
The Redundant Wireless Services zl Module supplies failover or availability
options within a wireless LAN, and uses the licenses of the primary Module.
Radio Ports as Layer 2 Devices
ProCurve Radio Ports are typically Layer 2 devices that use IEEE
802.3af-compliant Power over Ethernet (PoE). For Layer 2 operation, they
have no IP address and no user interface. ProCurve Radio Ports, attached
either directly to wireless services-enabled zl switch or directly to
infrastructure switches, communicate with a Wireless Edge Services zl
Module over an untagged interface using a custom protocol. This protocol
encapsulates station wireless traffic as well as management, control, and
status information sent between a radio port and a Module.
