Introduction
Building a Wireless LAN System
A Wireless LAN system contains a wireless services-enabled switch with
VLANs, radio ports, and WLANs,
Wireless Services-Enabled Switch
A wireless services-enabled Switch 5300xl is a 5300xl switch with a Module
installed. When used with and a number of distributed radio ports (RP)
providing the desired wireless LAN coverage. All of the ProCurve Radio Ports
are centrally managed through the Module. With the addition of a Module,
every wired port in a 5300 xl switch can support both wired and wireless
network traffic.
VLANs
VLANs on the 5300xl switch create paths between the Module, radio ports,
and the network. The Module requires two VLANs: Radio Port VLANs and
Uplink VLANs. The Radio Port VLAN sends and receives radio port traffic.
Uplink VLANs are used to send and receive traffic from the network.
The Radio Port VLAN provides connectivity to the radio ports and client
stations. Radio ports must be members of the Radio Port VLAN to be adopted
by and communicate with a Module. When software version E.10.30 (or later)
is loaded, the ProCurve Switch 5300xl uses LLDP (Link Layer Discovery
Protocol) and auto-provisioning to create a default Radio Port VLAN (VID
2100) when a radio port is connected directly to a 5300xl switch. Auto-
provisioning also creates a default Radio Port VLAN when a Module is
detected in a 5300xl switch chassis. If VLAN2100 is unavailable, the next
available VLAN is used.
When a radio port is not connected directly to a wireless services-enabled
Switch 5300xl:
■ the Radio Port VLAN must be configured on any switch between the radio
port and the wireless services-enabled Switch 5300xl.
■ the radio port must be an untagged member of the Radio Port VLAN on
the switch where it is connected.
The illustration below shows VLAN requirements when using a radio port
attached to an infrastructure, PoE-capable switch.
