Introduction

Radio Port VLAN

(Layer 3 Adoption)

When a radio port is placed in a Layer 2 domain different from the

Module’s, and the domains are separated by a router or routing switch,

Layer 3 Adoption must be used. For Layer 3 Adoption, a radio port must

be able to acquire an IP address from a DHCP server.

A VLAN with the Wireless Module’s IP address carries wireless traffic

as well as management, control, and status information sent between the

Module and radio ports. This VLAN contains either the Module’s internal

uplink or downlink port (but not both) as a tagged member.

This VLAN may span multiple switches and domains. Infrastructure

switches need to be configured with the necessary IP helper addresses

to ensure that the radio port can acquire the Module’s IP address (for

example, through special DHCP option 189 messages or DNS).

For detailed information on configuring Layer 3 Adoption, see “Radio Port

Adoption” in the latest Management and Configuration Guide for the

Wireless Edge Services zl Module.

Station A device (such as a wireless PC or printer) containing an IEEE 802.11-

conformant medium access control (MAC) and physical layer (PHY)

interface to the wireless medium.

Uplink Port The internal Module port that carries traffic to and from the network. The

uplink port may be a member of multiple VLANs; it must be a tagged

member of any uplink VLAN. This port is identified by the slot ID where

the Module is installed, appended with ‘UP.’ For example, “CUP” is the

uplink port for a Wireless Edge Services zl Module installed in slot C of a

zl switch.

Uplink Network

Ports

Any zl switch port that is a member of an uplink VLAN.

Uplink VLAN A VLAN containing the uplink port as a tagged member. By default, this

is the DEFAULT_VLAN (VLAN 1) on the zl switch. There may be more than

one uplink VLAN.

Wireless

Services-Enabled

ProCurve Switch

A ProCurve zl switch with a Wireless EDGE Services zl Module (or

Redundant Module) installed, capable of managing ProCurve Radio Ports

to deliver 802.11 wireless access to stations.
