Configuring AC System Parameters
Configuring the WLAN Mode
Procedure
- Run system-view
The system view is displayed.
- Run set workmode wlan ac
The device is configured to work in AC mode.
By default, the AR121W-S, AR101W-S, AR101GW-Lc-S, AR151W-P-S, AR161W-S, and AR1220W-S work in AP mode and other devices work in AC mode.
- Run quit
Exit from the system view.
- Run reboot [ fast ]
The device is restarted.
After the device is restarted, the AC mode takes effect.
Configuring Country Codes
Context
A country code identifies the country to which AP radios belong. Different countries support different AP radio attributes, including the transmit power and supported channels. Correct country code configuration ensures that radio attributes of APs comply with laws and regulations of countries and regions to which the APs are delivered.
- If the APs managed by an AC are located in the same country or region, you only need to configure one country code.
- If the APs managed by an AC are located in different countries, you need to configure different country codes for the APs.
When configuring an AC for the first time, you must configure the correct country code. The country code must comply with local laws and regulations.
Procedure
- Run system-view
The system view is displayed.
- Run wlan ac
The WLAN view is displayed.
- Run regulatory-domain-profile name profile-name
A regulatory domain profile is created, and the regulatory domain profile view is displayed.
By default, the system provides the regulatory domain profile default.
- Run country-code country-code
A country code is configured.
By default, the country code CN is configured.
For details about country codes, see country-code.
Modifying the country code in a regulatory domain profile will restart APs using the profile.
- Run quit
Return to the WLAN view.
- Bind the regulatory domain profile to an AP group or AP.
- Binding the regulatory domain profile to an AP group
Run the ap-group name group-name command to enter the AP group view.
Run the regulatory-domain-profile profile-name command to bind the regulatory domain profile to the AP group.
By default, the regulatory domain profile default is bound to an AP group.
- Binding the regulatory domain profile to an AP
- Run the ap-id ap-id, ap-mac ap-mac, or ap-name ap-name command to enter the AP view.
Run the regulatory-domain-profile profile-name command to bind the regulatory domain profile to the AP specific profile.
By default, no regulatory domain profile is bound to an AP.
- Binding the regulatory domain profile to an AP group
- Run quit
Return to the WLAN view.
- Run commit { all | ap-name ap-name | ap-id { ap-id1 [ to ap-id2 ] } &<1-10> }
Configurations are delivered to APs.
Configuring a Source Interface
Context
Each AC must have at least one VLANIF or loopback interface specified as the source interface. All APs connected to the AC can learn the IP address of this interface and use the IP address to communicate with the AC.
Before an AP establishes a CAPWAP tunnel with an AC, a source interface must be specified for the AC.
- VLANIF interface: applies to the scenario where the APs that associate with the AC belong to the same management VLAN.
- Loopback interface: applies to the scenario where the APs that associate with the AC belong to different management VLANs. When the APs belong to multiple management VLANs, the AC must have multiple VLANIF interfaces configured. If one of the VLANIF interfaces is specified as the source interface, all the APs cannot go online when the source interface fails. A loopback interface remains Up after being created. When a loopback interface is used as the source interface and a VLANIF interface becomes faulty, only the AP that connects to the VLANIF interface cannot go online.
Procedure
- Configure an IPv4 source interface.
Specify a VLANIF interface as the source interface.
