Managing the AP

Enabling the AP to connect to an AC

About this task

After this feature is enabled, the AP will discover ACs and select an optimal AC to connect to it. If this feature is disabled, the APs that have connected to the AC will go offline.

Procedure

1.     Enter system view.

system-view

2.     Enable the AP to connect to an AC.

wlan connect-ac enable

The default setting depends on the device model.

Configuring the default input power level

About this task

The power level of the AP can be high, middle, or low. The AP automatically obtains its input power level from the uplink switch at startup. If the AP fails to obtain its input power level, the AP operates at the configured default input power level.

An AP can be powered through a power adapter or through its PoE or PoE+ ports. The following table shows the relationship between the AP's power supply mode and input power level:

 

Power supply mode	Input power level
·     Power adapter. ·     Multiple PoE+ ports. ·     Combination of PoE and PoE+ ports.	High
·     Single PoE+ port ·     Multiple PoE ports	Middle
Single PoE port	Low

‌

An AP's support for MIMO modes and the USB interface varies by power level, as shown in Table 1.

Table 1 AP's support for MIMO modes and the USB interface

Input power level	Supported MIMO modes	Whether USB interfaces can be enabled
High	1×1, 2×2, 3×3, and 4×4.	Yes.
Middle	1×1, 2×2, 3×3, and 4×4.	Yes when the MIMO mode is 1×1 or 2×2.
Low	1×1.	No.

‌

Restrictions and guidelines

When you configure the default input power level for the AP, make sure the setting matches its power mode. An excessively low input power level prevents the AP from operating correctly. An excessively high input power level causes overload of the AP in case of power shortage.

Procedure

1.     Enter system view.

system-view

2.     Configure the default input power level.

Wlan power-level default { high | low | middle }

By default, the default input power level is middle.

Enabling or disabling the USB interface

About this task

After you enable the USB interface for the AP, the USB interface becomes active only when the input power level of the AP is middle or high.

If the input power level is middle, the MIMO mode can only be 1×1 or 2×2 with the USB interface enabled. With the USB interface disabled, the MIMO mode can reach 4×4.

2.     Enable the USB interface.

usb enable}

By default, the USB interface is disabled on the AP.

Setting a LED lighting mode

About this task

You can configure LEDs on the AP to flash in the following modes:

·     quiet—All LEDs are off.

·     awake—All LEDs flash once every minute.

·     always-on—All LEDs are steady on.

·     normal—This mode can identify the running status of an AP.

Procedure

1.     Enter system view.

system-view

2.     Set a LED lighting mode.

wlan led-mode { always-on | awake | normal | quiet }

By default, the LED lighting mode is normal.

Specifying a region code

About this task

A region code determines characteristics such as available frequencies, available channels, and transmit power level. Set a valid region code before configuring the AP.

To prevent regulation violation caused by region code modification, lock the region code.

Procedure

1.     Enter system view.

system-view

2.     Enter global configuration view.

wlan global-configuration

3.     Specify a region code.

region-code code

By default, the region code for APs in China is CN, and the region code for APs in Japan is JP. No region code is specified for APs in any other countries or regions.

4.     (Optional.) Lock the region code.

region-code-lock enable

By default, the region code is not locked.
