Introduction
ProCurve Wireless Edge Services xl Module
Note You also might need to perform some configuration tasks on the wireless
services-enabled switch, such as raising the maximum number of VLANs. (See
the ProCurve Series 6400cl Switches, 5300xl Switches, and 3400cl Switches
Management and Configuration Guide and ProCurve Series 6400cl
Switches, 5300xl Switches, and 3400cl Switches Advanced Traffic Manage-
ment Guide.)
Dynamically Establishing a Radio Port VLAN. If the RP authenticates
itself to a RADIUS server, this server may send a dynamic VLAN assignment
to the switch to which the RP connects. The switch configures the RP’s port
as an untagged member of the dynamic VLAN.
Both infrastructure and wireless services-enabled switches can receive set-
tings for dynamic Radio Port VLANs, depending, of course, on their capabili-
ties. The dynamic VLAN takes precedence over both manually configured and
auto-provisioned settings.
See “802.1X Default Client” on page 1-46 for more information on how
ProCurve RPs authenticate themselves.
Communicating with the Ethernet Network: Uplink VLANs
The Wireless Edge Services xl Module sends and receives Ethernet network
traffic on the uplink VLANs.
By default, the only uplink VLAN is VLAN 1, and the module’s internal uplink
port is tagged for this VLAN. As for any switch port, you must tag the uplink
port for other VLANs if you want the module to forward network traffic in
those VLANs.
Recall that the module receives traffic from RPs in a Radio Port VLAN. Before
forwarding the traffic, it must place it in one of the uplink VLANs. The module
does so according to the VLAN assignment stored in the association with the
wireless station that sent the traffic.
This VLAN assignment is quite important as it determines the subnet in which
wireless stations are placed, as well as the type of network access they receive.
When the user authenticates and associates, the module makes the assign-
ment as follows:
■ If a RADIUS server sends a dynamic VLAN assignment for that user, the
module assigns the station to that VLAN.
■ Otherwise, the module determines the WLAN to which the station belongs
and assignees it to the VLAN specified for that WLAN.
