Disable

The following scenario shows how to disable a WLAN interface (i.e, halt any selected WLAN network) and disable a radio module (i.e., halt any network configured on top of the selected module).

Disable Interface

Description

In this example, WLAN interfaces wlan4 will be disabled using the disable command.

Scenario

Step 1: 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 address 192.168.100.1/24
set interfaces wlan wlan4 bridge-group bridge br0
set interfaces wlan wlan4 phy wifi1
set interfaces wlan wlan4 type access-point security akm none
set interfaces wlan wlan4 type access-point ssid network1_2.4GHz
set interfaces wlan wlan5 bridge-group bridge br0
set interfaces wlan wlan5 phy wifi1
set interfaces wlan wlan5 type access-point security akm none
set interfaces wlan wlan5 type access-point ssid network2_2.4GHz
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Note

By default, when a WLAN interface is created, it will start working after commit.

Step 2: Run the command interfaces wlan wlan4 show status at DUT0 and check that the interface wlan4 status is up:

Show output

Interface: wlan4
        Mode: access-point
       Radio: wifi1
      Status: up
       BSSID: 12:68:38:c6:f4:7c
        SSID: network1_2.4GHz
    Stations: 0

Step 3: Configure the MON device to connect to network1_2.4GHz using the following configuration:

set controllers wlan installation indoor
set controllers wlan radios wifi0 bandwidth 20MHz
set interfaces wlan wlan0 phy wifi0
set interfaces wlan wlan0 type station network 1 bssid 12:68:38:c6:f4:7c
set interfaces wlan wlan0 type station network 1 ssid network1_2.4GHz
set system wlan log-level configuration debug
set interfaces wlan wlan0 address 192.168.100.10/24
set interfaces wlan wlan0 type station network 1 security akm none

Step 4: Ping IP address 192.168.100.1 from MON:

admin@MON$ ping 192.168.100.1 count 2 size 56 timeout 1

Show output

PING 192.168.100.1 (192.168.100.1) 56(84) bytes of data.
64 bytes from 192.168.100.1: icmp_seq=1 ttl=64 time=20.5 ms
64 bytes from 192.168.100.1: icmp_seq=2 ttl=64 time=3.82 ms

--- 192.168.100.1 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 3ms
rtt min/avg/max/mdev = 3.815/12.181/20.548/8.367 ms

Step 5: Modify the following configuration lines in DUT0 :

set interfaces wlan wlan4 disable

Note

When disabled, a WLAN interface will be down meaning no connection is possible.

Step 6: Run the command interfaces wlan wlan4 show status at DUT0 and check that the interface wlan4 status is down:

Show output

Interface: wlan4
        Mode: access-point
       Radio: wifi1
      Status: down

Step 7: Expect a failure in the following command: Configure the MON device to connect to network1_2.4GHz using the following configuration:

set controllers wlan installation indoor
set controllers wlan radios wifi0 bandwidth 20MHz
set interfaces wlan wlan0 phy wifi0
set interfaces wlan wlan0 type station network 1 bssid 12:68:38:c6:f4:7c
set interfaces wlan wlan0 type station network 1 ssid network1_2.4GHz
set system wlan log-level configuration debug
set interfaces wlan wlan0 address 192.168.100.10/24
set interfaces wlan wlan0 type station network 1 security akm none

Disable Controller

Description

In this example, radio interfaces wifi1 will be disabled using the disable command. As a result, WLAN interfaces wlan4 and wlan5 will be disabled as well.

Scenario

Step 1: 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 address 192.168.100.1/24
set interfaces wlan wlan4 bridge-group bridge br0
set interfaces wlan wlan4 phy wifi1
set interfaces wlan wlan4 type access-point security akm none
set interfaces wlan wlan4 type access-point ssid network1_2.4GHz
set interfaces wlan wlan5 bridge-group bridge br0
set interfaces wlan wlan5 phy wifi1
set interfaces wlan wlan5 type access-point security akm none
set interfaces wlan wlan5 type access-point ssid network2_2.4GHz
set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'

Note

Like a WLAN interface, a WLAN radio will work after commit if the configuration is right.

Step 2: Run the command interfaces wlan wlan4 show status at DUT0 and check that the interface wlan4 status is up:

Show output

Interface: wlan4
        Mode: access-point
       Radio: wifi1
      Status: up
       BSSID: 12:68:38:c6:f4:7c
        SSID: network1_2.4GHz
    Stations: 0

Step 3: Run the command interfaces wlan wlan5 show status at DUT0 and check that the interface wlan5 status is up:

Show output

Interface: wlan5
        Mode: access-point
       Radio: wifi1
      Status: up
       BSSID: 12:68:38:c6:f5:7c
        SSID: network2_2.4GHz
    Stations: 0

Step 4: Configure the MON device to connect to network1_2.4GHz using the following configuration:

set controllers wlan installation indoor
set controllers wlan radios wifi0 bandwidth 20MHz
set interfaces wlan wlan0 phy wifi0
set interfaces wlan wlan0 type station network 1 bssid 12:68:38:c6:f4:7c
set interfaces wlan wlan0 type station network 1 ssid network1_2.4GHz
set system wlan log-level configuration debug
set interfaces wlan wlan0 address 192.168.100.10/24
set interfaces wlan wlan0 type station network 1 security akm none

Step 5: Ping IP address 192.168.100.1 from MON:

admin@MON$ ping 192.168.100.1 count 2 size 56 timeout 1

Show output

PING 192.168.100.1 (192.168.100.1) 56(84) bytes of data.
64 bytes from 192.168.100.1: icmp_seq=1 ttl=64 time=13.6 ms
64 bytes from 192.168.100.1: icmp_seq=2 ttl=64 time=3.82 ms

--- 192.168.100.1 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 3ms
rtt min/avg/max/mdev = 3.820/8.707/13.595/4.888 ms

set controllers wlan installation indoor
set controllers wlan radios wifi0 bandwidth 20MHz
set interfaces wlan wlan0 phy wifi0
set interfaces wlan wlan0 type station network 1 bssid 12:68:38:c6:f5:7c
set interfaces wlan wlan0 type station network 1 ssid network2_2.4GHz
set system wlan log-level configuration debug
set interfaces wlan wlan0 address 192.168.100.10/24
set interfaces wlan wlan0 type station network 1 security akm none

Step 7: Ping IP address 192.168.100.1 from MON:

admin@MON$ ping 192.168.100.1 count 2 size 56 timeout 1

Show output

PING 192.168.100.1 (192.168.100.1) 56(84) bytes of data.
64 bytes from 192.168.100.1: icmp_seq=1 ttl=64 time=6.75 ms
64 bytes from 192.168.100.1: icmp_seq=2 ttl=64 time=67.3 ms

--- 192.168.100.1 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 3ms
rtt min/avg/max/mdev = 6.745/37.043/67.342/30.299 ms

Step 8: Modify the following configuration lines in DUT0 :

set controllers wlan radios wifi1 disable

Note

Connecting with wlan4 and wlan5 is not possible since both interfaces are down.

Step 9: Run the command interfaces wlan wlan4 show status at DUT0 and check that the interface wlan4 status is down:

Show output

Interface: wlan4
        Mode: access-point
       Radio: wifi1
      Status: down

Step 10: Run the command interfaces wlan wlan5 show status at DUT0 and check that the interface wlan5 status is down:

Show output

Interface: wlan5
        Mode: access-point
       Radio: wifi1
      Status: down

Step 11: Expect a failure in the following command: Configure the MON device to connect to network1_2.4GHz using the following configuration:

set controllers wlan installation indoor
set controllers wlan radios wifi0 bandwidth 20MHz
set interfaces wlan wlan0 phy wifi0
set interfaces wlan wlan0 type station network 1 bssid 12:68:38:c6:f4:7c
