1.2.2.5 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 SSID configured
differently in 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 in Radius Server.
1.2.2.6 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 4-53
1.2.2.7 Self Healing
Self Healing is the ability to dynamically adjust the RF network by modifying transmit power and/or
supported rates, based on an AP failure.
In a typical RF network deployment, the APs are configured for Transmit Power below its maximum level. This
allows the Tx Power to be increased when there is a need to increase coverage whenever an AP fails.
When an AP fails, the Tx Power/Supported rates of APs neighboring the failed AP is adjusted. The Tx power
is increased and/or Supported rates are decreased. When the failed AP becomes operational again, the
Neighbor AP’s Tx Power/Supported rates are brought back to the levels in operation before the self healing
operation changed them.
The switch detects an AP failure when:
• AP stops sending heartbeats.
• AP beacons are no longer being sent.
Configure 0 (Zero) or more APs to act as either:
• Detector APs — Detector APs scan all channels and send beacons to the switch which uses the
information for self-healing.
• Neighbor APs — When an AP fails, neighbor APs assist in self healing.
