Parameter Description
DTIM interval The DTIM interval indicates the delivery traffic indication message (DTIM) period in
beacons, which can be configured for every WLAN SSIDprofile. The DTIMinterval
determines how often the W-IAP should deliver the buffered broadcast and multicast
frames to associated clients in the powersave mode. The default value is 1, which means
the client checks for buffered data on the W-IAP at every beacon. You can also configure a
higher DTIM value for power saving.
Min RSSI probe
request
Sets a minimum Received signal strength indication (RSSI) threshold for probe requests.
Min RSSI auth request Sets a minimum RSSI threshold for authentication requests.
Very high throughput Enables VHT function on W-IAP devices that support VHT. For 802.11acW-IAPs, the VHT
function is enabled by default. However, you can disable the VHT function if you want the
802.11ac W-IAPs to function as 802.11n W-IAPs.
If VHT is configured or disabled on an SSID, the changes will apply only to the SSID on
which it is enabled or disabled.
Zone Specify the zone for the SSID. When the zone is defined in SSID profile and if the same
zone is defined on a W-IAP, the SSID is created on that W-IAP. For more information on
configuring zone details, see Configuring Zone Settings on a W-IAP on page 63.
The following constraints apply to the zone configuration:
l A W-IAP can belong to only one zone and only one zone can be configured on an SSID.
l If an SSID belongs to a zone, all W-IAPs in this zone can broadcast this SSID. If no W-IAP
belongs to the zone configured on the SSID, the SSID is not broadcast.
l If an SSID does not belong to any zone, all W-IAPs can broadcast this SSID.
Time Range Click Edit, select a Time Range Profile from the list and specify if the profile must be
enabled or disabled for the SSID, and then click OK.
Bandwidth Limits Under Bandwidth Limits:
l Airtime—Select this check box to specify an aggregate amount of airtime that all
clients in this network can use for sending and receiving data. Specify the airtime
percentage.
l Each radio—Select this check box to specify an aggregate amount of throughput that
each radio is allowed to provide for the connected clients.
l Downstream and Upstream—Specify the downstream and upstream rates within a
range of 1 to 65,535 Kbps for the SSID users. If the assignment is specific for each user,
select the Peruser check box.
Wi-Fi Multimedia
(WMM) traffic
management
Configure the following options for WMM traffic management. WMM supports voice, video,
best effort, and background access categories. To allocate bandwidth for the following
types of traffic, specify a percentage value under Share. To configure DSCP mapping,
specify a value under DSCP Mapping.
l Background WMM—For background traffic such as file downloads or print jobs.
l Best effort WMM—For best effort traffic such as traffic from legacy devices or traffic
