Band Configuration

Description

In this example, a WLAN interface will be created on top of the 2.4GHz or 5GHz radio module in access-point mode. Then, correct operation will be checked using operational commands and a WLAN client.

Scenario

Example 1

Step 1: Get the supported Bands from wifi1 capabilities list:

admin@DUT0$ controllers wlan radios wifi1 show capabilities
Show output
Radio: wifi1
                   Type: physical
                    Phy: mwiphy1
                  Bands: 2.4GHz
             Bandwidths: 20MHz,40MHz
                  Modes: 802.11g,802.11n
     Supported channels: 1,2,3,4,5,6,7,8,9,10,11,12,13,14
        Spatial streams: 2
          Max. TX power: 20dBm (100.0mW)
          Max. stations: 64
        Max. interfaces: 2
        HT capabilities: LDPC,TX-STBC,RX-STBC1

Step 2: Run command configure at DUT0 and expect this output: Step 3: Run command delete interfaces wlan at DUT0 and expect this output:

Show output
Nothing to delete (the specified node does not exist)

Step 4: Run command delete controllers wlan at DUT0 and expect this output:

Show output
Nothing to delete (the specified node does not exist)

Step 5: Run command commit at DUT0 and expect this output: Step 6: Set the following configuration in DUT0 :

set controllers wlan radios wifi1 band 2.4GHz
set controllers wlan radios wifi1 channel 1
set interfaces bridge br0
set interfaces wlan wlan4 bridge-group bridge br0
set interfaces wlan wlan4 phy wifi1
set interfaces wlan wlan4 type access-point security akm none

Note

Note that the band must be set to 2.4GHz, which is the value previously obtained.

Step 7: Wait until the wlan4 interface of DUT0 is up. When so, check that the base radio module wifi1 is also up. Note that the CAC procedure could delay this process up to 10 mins depending on the selected channel.
