4. Prepare to configure the parameters in one of the following ways:
{
On the Wireless Service Information tab, click the Modify icon for the global parameter
information.
{
In the Wireless Service area to the right of the page, click the Global Configuration link.
The Fat AP Parameter Configuration page appears.
5. Set the following parameters as needed:
{
Client Keep-Alive Interval (s)—Enter the client keep-alive interval. The keep-alive mechanism
is used to detect clients segregated from the system. The fat AP sends probe requests to a
client. If the fat AP cannot receive any response, it terminates the connection with the client.
{
Client Idle-Timeout Interval (s)—Enter the maximum interval for which the link between the fat
AP and a client can be idle. If the fat AP does not receive any frame sent by the client within
the maximum interval, the fat AP terminates the connection with the client.
{
Country/Region Code—Specify the code of the country or district to which the fat AP
belongs, such as US (United States) and CN (China). The working channel of a radio varies
with country codes. If the channel scanning mode is Auto, the country code of the fat AP
determines the channels scanned by the fat AP.
{
Work Mode—Specify an operating mode. Options are Normal, Monitor, and Hybrid.
Operating in normal mode, the fat AP only provides WLAN services for clients. Operating in
monitor mode, the fat AP monitors all devices in the WLAN, but it does not provide WLAN
services. Operating in hybrid mode, the fat AP can both scan devices in the WLAN and act
as a wireless access point.
6. Click OK.
