●
U ser based VLAN assignment — Allows the controller to extract Virtual LAN (VLAN) information
from the Radius server.
●
User based QoS — Enables Quality of Service (QoS) for the MU based on settings within the Radius
Server.
Voice Prioritization
The controller 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 Wi-Fi Multimedia (WMM) supported voice devices)
additional priority.
Currently voice support implies the following:
●
Spectralink voice prioritization - Spectralink sends packets that allow the controller 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 196 .
Wireless Capacity
Wireless capacity specifies the maximum numbers of MUs, Access Points and wireless networks usable
by a controller. Wireless capacity is largely independent of performance. Aggregate controller
performance is divided among the controller clients (MUs and Access Points) to find the performance
experienced by a given user. Each controller platform is targeted at specific market segments, so the
capacity of each platform is chosen appropriately. Wireless controller capacity is measured by:
●
The maximum number of WLANs per controller
●
The maximum number of Access Points adopted per controller
●
The maximum number of MUs per controller
●
The maximum number of MUs per Access Point
The actual number of Access Points adoptable by a controller is defined by the controller licenses or the
total licenses in the cluster in which this controller is a member.
AP Load Balancing
At adoption, the AP solicits and receives multiple adoption responses from the controllers on the
network. These adoption responses contain preference and loading information the AP uses to select the
optimum controller to be adopted by. Use this mechanism to define which APs are adopted by which
controllers. By default, the adoption algorithm generally distributes AP adoption evenly among the
controllers available.
