8. A RADIUS server authenticates the user.
9. Upon successful authentication, the user is directed to a Welcome Page that lists (among other
things) an Acceptable Use Policy.
10. The user agrees to the usage terms and is granted access to the Internet. (or other network
services).
To setup a hotspot, create a WLAN ESSID and select Hotspot authentication from the
Authentication menu. This is simply another way to authenticate a WLAN user, as it would be
impractical to authenticate visitors using 802.1x. For information on configuring a hotspot, see
“Configuring hotspots” on page 107.
IDM (identity driven management)
RADIUS authentication is performed for all protocols using a RADIUS-based authentication scheme
(such as EAP). Identity driven management is provided using a RADIUS client. The following IDMs
are supported:
• User based SSID authentication — Denies authentication to MUs if associated to a ESSID
configured differently by their RADIUS server.
• User based VLAN assignment — Allows the switch to extract VLAN information from the RADIUS
server.
• User based QoS — Enables QoS for the MU based on settings within the RADIUS Server.
Voice prioritization
The switch has the capability of having its QoS policy configured to prioritize network traffic
requirements for associated MUs. Use QoS to enable voice prioritization for devices using voice as
its transmission priority.
Voice prioritization allows you to assign priority to voice traffic over data traffic, and (if necessary)
assign legacy voice supported devices (non WMM supported voice devices) additional priority.
Currently voice support implies the following:
• Spectralink voice prioritization - Spectralink sends packets that allow the switch to identify
these MU's as voice MU's. Thereafter, any UDP packet sent by these MU's is prioritized ahead
of data.
• Strict priority - The prioritization is strict.
• Multicast prioritization - Multicast frames that match a configured multicast mask bypass the
PSP queue. This features permits intercom mode operation without delay (even in the
presence of PSP MU's).
For more information on configuring voice prioritization for a target WLAN, see “Configuring WMM”
on page 137 .
Self healing
Self healing is the ability to dynamically adjust the RF network by modifying transmit power and/or
supported rates upon an AP failure.
In a typical RF network deployment, APs are configured for Transmit Power below their maximum
level. This allows the Tx Power to be increased when there is a need to increase coverage when an
AP fails.
