Click OK and COMMIT, to save the configured parameters. REBOOT the device, if you have changed any of the parameters
marked asterisk marked against it.
WDS Optimization
Mode
DTIM
(Delivery Traffic
Indication Map)
Specifies the number of beacon frames that can be transmitted before another DTIM is
transmitted. An increase in the DTIM period count, allows clients to sleep longer. However, it
delays the delivery of multicast and unicast packets.
By default, it is 3. To configure, enter a value ranging from 1 to 255 in the DTIM box.
: Long DTIM intervals will allow the mobile wireless clients to sleep for longer hours
thus maximizing the battery life. With short DTIM intervals, frequent frame delivery
takes place thus reducing the power save efficiency of the battery.
Rogue Scan Status Specifies the status of the Rogue Scan feature on the AP device. Rogue Scan allows you to
scan and monitor all the wireless devices (AP/STA/WDS/ADHOC) and rogue AP devices,
within its vicinity and provides statistics of the interference caused by those devices.
Rogue Scanning is done via two modes:
a. Current Channel Scan: In this mode, the AP device scans all the wireless devices
and rogue AP devices in the current operating channel, simultaneously performing
the standard AP functionality.
• AP device listens to all the data packets transmitted over the current
operating channel, interprets the beacons and probe responses from the
neighboring devices and maintains its BSS throughput performance.
• A maximum of 32 wireless devices can be scanned. Once it exceeds the
limit of 32 entries, it overwrites the oldest entry.
b. All Channel Scan: In this mode, the AP device continuously scans all the available
channels (both active and passive, depending on the channel flags) within its
vicinity. A maximum of 512 wireless devices can be scanned.
By default, Rogue Scan Status is disabled. To enable select either Current Channel Scan
or All channel Scan from the drop down menu.
:
• When Auto Channel Selection is enabled, Rogue Scan Status cannot be set to All
Channel Scan.
• In All Channel Scan mode, the AP device does not support complete AP functionality.
Rogue Scan Period This parameter is enabled when Rogue Scan Status is set to All channel Scan. This
parameter specifies the time period for which, the AP device scans each available channel to
detect every wireless device in its vicinity.
By default, it is 250ms. To configure, enter the time period value between 100- 1000ms.
: When WDS optimization mode is enabled with configured channel
bandwidth of 40 MHz (i.e Dynamic 20/40 Mode), AP will not dynamically
switch to 20 MHz bandwidth, when it finds extension channel is busy.
