Modifying radio parameters for a fat AP
This function allows you to modify radio parameters for a fat AP, and bind and unbind radios to
service policies. When you bind a service policy to a radio, you must specify a wireless logical
interface to determine the authentication method and the VLAN for clients.
To modify radio parameters for a fat AP:
1. Click the Service tab.
2. From the navigation tree, select WLAN Manager > Resource Management > Fat APs.
The Fat AP List page displays all fat APs.
3. Click the device label of the target fat AP.
4. In the Radio Information area on the Wireless Service Information tab, click Modify.
5. Set the following parameters as needed:
{
Radio ID—This field cannot be modified.
{
Beacon Interval (TU)—Enter the interval for the fat AP to send beacon frames.
{
DTIM Interval—Enter the number of beacon intervals an AP waits before it sends buffered
multicast and broadcast frames. The value is in the range of 1 to 31. The default value is 1,
which equals 102,400 microseconds. The AP sends buffered broadcast/multicast frames
when the DTIM counter reaches the configured value.
{
RTS Threshold (bytes)—Enter the length of frames for which the RTS method is used. Set a
rational value to effectively avoid data sending collisions in a WLAN. If you set a small value,
RTS packets are sent frequently, consuming more of the available bandwidth. However, the
system can recover quickly from interference or collisions.
{
Fragment Threshold (bytes)—Enter the maximum length of frames that can be transmitted
without fragmentation. A frame that exceeds the specified fragment threshold is fragmented.
{
Short Frame Retransmission Threshold—Enter the maximum number of attempts to transmit a
frame shorter than the RTS threshold.
{
Long Frame Retransmission Threshold—Enter the maximum number of attempts to transmit a
frame larger than the RTS threshold.
{
Rx Lifecycle (ms)—Enter the interval for the fat AP to hold a received frame in its buffer
memory.
{
Radio Type—Specify a radio type. Options are 802.11a, 802.11b, 802.11g, 802.11gn, and
802.11an. If you specify 802.11gn or 802.11an, set the following parameters: Enable A-MPDU,
Enable A-MSDU, Client 802.11n Only, and Short GI.
The type of a radio cannot be modified if the radio has been bound to an enabled mesh
profile.
{
Channels in Use—Specify the working channel of the radio. If this field displays Auto, the fat
AP selects an idle channel as the working channel.
{
Max Transmission Power (dBm)—Enter the maximum transmit power of the radio, in dBm.
{
Current Transmission Power (dBm)—Current transmission power of the radio, in dBm.
{
MP Policy—Specify an MP policy bound to the radio, including existing MP policies in WSM.
{
Mesh Profile ID—Specify a mesh profile ID bound to the radio.
6. Perform one of the following steps:
{
Check a selected service policy to unbind the service policy to the radio.
