Advanced Options
The advanced options can be used to configure special WLANs; for example, you
might want to create a special WLAN for VoIP phone use only, or create a student
WLAN that should be time-controlled to provide access only during school hours.
• Accounting Server : If you added a RADIUS Accounting server on the AAA servers
page, select the RADIUS Accounting server from the drop-down list, and then
set the accounting update interval in
Send Interim-Update every x minutes
.
Valid Interim-Update values are 0-1440. Setting the value to 0 disables periodic
interim updates to the accounting server, but client IP changes are still sent to
the RADIUS Accounting server.
• Access Controls : Toggle this drop-down list to select Access Control Lists (L2
or L3/L4), Device Policy and Precedence Policy to apply to this WLAN. An access
control entry must be created before being available here. For more information,
see
Controlling Network Access Permissions .
• Enable Role based Access Control Policy : This feature allows different user
groups to have different access policies based on their user roles using the same
WLAN. See
Role Based Access Control Policy .
• 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 suffi-
cient 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
