awaiting pickup. Specify a DTIM period within the given range (1-255). The
measurement is in beacons. For example, if you set this field to 1, clients will check
for buffered data on the AP at every beacon. If you set this field to 10, clients will
check on every 10th beacon.
Specify the interval of beacon frames transmitted by an access point to announce
the existence of the wireless network. The default behavior is to send a beacon
frame once every 100 milliseconds (or 10 per second). The Beacon Interval value
is set in milliseconds. Enter a value from 20 to 2000.
Tick the check box to enable load balancing. When enabled, you can control the
amount of traffic that is allowed on the AP.
Enter a threshold for the percentage of network bandwidth utilization allowed on the
radio. Once the level is reached, the AP stops accepting new client associations.
Specify the maximum number of stations allowed to associate with this access
point.
Tick the check box to make the radio of APs assigned to this profile eligible for
auto-channel selection.
Tick the check box to automatically adjust the RF signal to broadcast at the right
distance.
Enter a percentage of the maximum transmission power for the RF signal. When
the Automatic Power check box is selected, an initial default RF signal power
setting is used. Alternatively, a fixed RF signal power setting is used. The
automatic RF signal power algorithm will not reduce the RF signal power below the
number you set in this field. By default, the value is 100%.
Tick the check box to allow
channel to scan other channels.
Tick the check box to allow the radio to operate in sentry mode.
Enter the length of time between channel changes during the RF Scan.
The radio can scan channels in the radio frequency used by the 802.11b/g/n and
(2.4 GHz), the 802.11a/n band (5 GHz), or both bands. Select the channel band for
the radio to scan.
Enter the amount of time in milliseconds that the radio spends scanning the other
channel during an RF scan.
Enabling multicast and broadcast rate limiting can improve overall network
performance by limiting the number of packets transmitted across the network.
Enter the rate limit to set for multicast and broadcast traffic.
Enter a rate limit burst determines how much traffic bursts can be before all traffic
exceeds the rate limit.
Use the drop-down menu to restrict the use of the channel bandwidth to 20 MHz or
40 MHz.
Select Auto to guarantee that 802.11 transmissions do not cause interference with
legacy stations or applications. Select Off to disable the protection mechanism.
Select Enable to send the same data stream on multiple antennas at the same
time.
Select Enable to specify that the AP should not acknowledge frames with
QosNoAck as the service class value.
Select Enable to enable Unscheduled Automatic Power Save Delivery (UAPSD),
which is a power management method.
Enter a number to limit the size of packets transmitted over the network. Any
packet under the entered size is not fragmented. Entering 2346 means that packets
are not fragmented.
Display the maximum number of transmission attempts on frame sizes less than or
the radio periodically moves away from the operational
