• Application Recognition and Control : Enable this option to allow APs to collect
client application data, which can then be consolidated for use by the Applications
and Top 10 Applications by Usage graphs.
NOTE Supported APs: H500, R300, R310, R500, R510, R600, R700, R710, R720,
T300 series, T710 series, 7055, 7352, 7372, 7781/7782 series, 7982.
NOTE When Application Recognition and Control is enabled, the Apply Policy
group option becomes available. Use this option to apply an Application Policy to
this WLAN (see Configure Application Policies on page 117).
• Call Admission Control (Disabled by default): Enable WiFi 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. (You will also need
to enable Call Admission Control on any APs supporting this WLAN from the
Configure > Access Points page.)
• Rate Limiting : 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.
• SSID Rate Limiting : In addition to per-station rate limiting, admins can also limit the
total bandwidth of all clients connected to the same SSID of an AP, across both 2.4
GHz and 5 GHz radios. The bandwidth limits are applied to each radio according to
the number of clients connected, so for example, if there are 7 clients connected to
the 2.4 GHz radio and 3 clients connected to the 5 GHz radio, and the total bandwidth
configured in SSID rate limiting is 10 Mbps, then the 7 clients in the 2.4 GHz band
would share 7 Mbps, while the other 3 clients in the 5 GHz band would share the
remaining 3 Mbps.
NOTE Per-station rate limiting is disabled if per-SSID rate limiting is enabled.
