Advanced Options - Ruckus Wireless ZoneDirector 1100 User Manual

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 the ACL to apply to this WLAN. An
ACL must be created before being available here. For more information, see
Access Control Lists"
• 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. (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.
• Multicast Filter: When enabled for a WLAN, all client multicast traffic will be dropped at the
AP. Broadcast and unicast frames remain unchanged.
• Access VLAN: By default, all wireless clients associated with APs that ZoneDirector is
managing are segmented into a single VLAN (with VLAN ID 1). If you want to tag this WLAN
traffic with a different VLAN ID, enter a valid VLAN ID (2-4094) in the box. Select the Enable
Dynamic VLAN check box to allow ZoneDirector to assign VLAN IDs on a per-user basis.
Before enabling dynamic VLAN, you need to define on the RADIUS server the VLAN IDs
that you want to assign to users. See
information.
