13.Refer to the 

 field for the current state of the requests made from applet. This field displays error 

messages if something goes wrong in the transaction between the applet and the switch.

14.Click 

 to use the changes to the running configuration and close the dialog.

15.Click 

 to close the dialog without committing updates to the running configuration.

Use the 

 screen to define a set of basic and supported rates for the target radio. This allows 

the radio to sync with networks using varying data rates and allows the radio to default to a predefined set 
of data rates when higher data rates cannot be maintained. 

To configure Rate Settings for a radio:

1. Click the

button within the radio edit screen to launch a new screen with rate setting 

information.

2. Check the boxes next to all the 

 you want supported. 

Basic Rates are used for management frames, broadcast traffic and multicast frames. If a rate is selected 
as a basic rate it is automatically selected as a supported rate. 

3. Check the boxes next to all the 

 you want supported. 

When an access port increases its power to compensate for a failure, power is increased to 
the country's regulatory maximum. Set the Self Healing Offset to reduce the country's 
regulatory maximum power if access ports are situated close to each other or if access port 
uses an external antenna. For additional information on determining the offset value, see the 
documentation shipped with the access port.

Select the DTIM Periods button to specify a period for Delivery Traffic Indication Messages 
(DTIM) for BSS IDs 1-4. This is a divisor of the beacon interval (in milliseconds), for example, 
10 : 100. (See "Beacon Interval," above). A DTIM is periodically included in the beacon frame 
transmitted from adopted access ports. The DTIM period determines how often the beacon 
contains a DTIM, for example, 1 DTIM for every 10 beacons. The DTIM indicates that 
broadcast and multicast frames (buffered at the access port) are soon to arrive. These are 
simple data frames that require no acknowledgement, so nodes sometimes miss them. 
Increase the DTIM/beacon settings (lengthening the time) to let nodes sleep longer and 
preserve their battery life. Decrease these settings (shortening the time) to support 
streaming-multicast audio and video applications that are jitter-sensitive. The default DTIM 
period is 10 beacons for BSS 1-4.
