The WLAN > Advanced Options > Access Control page provides the following
- Call Admission Control: (Disabled by default). Enable Wi-Fi Multimedia
Admission Control (WMM-AC) to support Polycom/Spectralink VIEW certification. When enabled, the
AP announces in beacons if admission control is mandatory or not for various access categories
and admits only the traffic streams it can support based on available network resources. When
network resources are not sufficient to provide this level of performance, the new traffic
stream is not admitted. Call Admission Control is effective only when both AP and the client
support WMM-AC. Ruckus APs are capable of handling hundreds of simultaneous clients, but when it
comes to VoIP traffic, the number of VoIP calls needs to be policed to ensure adequate
voice/video quality. Ruckus recommends limiting bandwidth allocation to six calls (four active
calls and two reserved for roaming) on the 2.4 GHz radio and 10 calls on the 5 GHz radio (seven
active and three reserved for roaming). Enable this feature if you want this WLAN to serve as a
VoIP WLAN to support Spectralink phones.
- Rate Limit: Rate limiting controls fair access to the network. When
enabled, the network traffic throughput of each network device (i.e., client) is limited to the
rate specified in the traffic policy, and that policy can be applied on either the uplink or
downlink. Toggle the Uplink and/or Downlink drop-down lists to limit the rate at which WLAN
clients upload/download data. The "Disabled" state means rate limiting is disabled; thus,
traffic flows without prescribed limits.
- Access Control: Toggle this drop-down list to select Access Control
Lists (L2 or L3/L4) and Device Policy to apply to this WLAN. An access control entry or a device
policy must be created before being available here. For more information, see Access Control.
- Application Visibility: Enable this option to allow APs to collect
client application data, which can then be consolidated for use by the Application Recognition and Control pie charts.
- Apply Policy Group: This option allows the administrator to deny
application access by blocking any HTTP host name or L4 port. Using application denial
policies, administrators can block specific applications if they are seen to be consuming
excessive network resources, or enforce network usage policies such as blocking social media
sites. (For more information, see Application Denial Policies.)
