frequency

Function

The frequency command sets the working frequency of radio 0 to the 5 GHz frequency band.

The undo frequency command restores the working frequency of radio 0 to the 2.4 GHz frequency band.

By default, radio 0 works on the 2.4 GHz frequency band, and radio 2 works on the 5 GHz frequency band.

Format

frequency { 2.4g | 5g }

undo frequency

Parameters

None.

Usage Guidelines

Usage Scenario

On APs supporting radio switching between the 2.4 GHz and 5 GHz frequency bands, some radios support both the two bands. However, such radios can work on one band at a time. You can configure the working frequency band of the AP based on the frequency band of STAs.

Precautions

When working in dual-5G mode, some APs support only low-band channels (36 to 64) or high-band channels (100 to 165) on the 5 GHz band.
  • AP4030TN: Radio 0, radio 1, and radio 2 on all bands
  • AP8130DN: Radio 0 and radio 1 on all bands
  • AP8150DN: Radio 0 and radio 1 on all bands
  • AP6052DN: Radio 0 on low bands and radio 1 on high bands
  • AP7052DN: Radio 0 on low bands and radio 1 on high bands
  • AP7152DN: Radio 0 on low bands and radio 1 on high bands
  • AP8182DN: Radio 0 on low bands and radio 1 on high bands
  • AP4051TN: Radio 1 on high bands and radio 2 on low bands
  • AP8050TN-HD: Radio 1 on high bands and radio 2 on low bands

Changing the working frequency of radio 0 and radio 2 will delete the channel, power, and antenna gain configurations on radio 0 and radio 2. If an AP uses an external antenna, run the antenna-gain antenna-gain command to reconfigure the antenna gain to be consistent with the gain of the external antenna connected to the AP.

If an AP works in dual-5G mode, the channels of the two 5G radios must be separated by at least one channel.

For example, a country supports 40 MHz 5G channels 36, 44, 52, and 60. When deploying 5G radio channels, if one radio is deployed on channel 36, it is recommended that the other radio be deployed on channel 52 or 60. Channel 44 is not recommended in this case.

Example

# Set the working frequency to the 5 GHz frequency band for radio 0 of AP.
