Country Code on WLC

Controllers and access points are designed for use in many countries with varying regulatory requirements. The radios within the access points are assigned to a specific regulatory domain at the factory (such as –E for Europe), but the country code enables you to specify a particular country of operation (such as FR for France or DE for Germany). Configuring a country code ensures that each radio’s broadcast frequency bands, interfaces, channels, and transmit power levels are compliant with country-specific regulations.

Generally, we configure one country code per controller, the one matching the physical location of the controller and its access points. However, controller software release 4.1 or later releases allows us to configure up to 20 country codes per controller. This multiple-country support enables us to manage access points in various countries from a single controller. This rule is not application for MESH Access Points.

*** Note: Mesh AP doesn’t support Multi country code on WLC.

*** We can not change the country’s regulatory domain on Access Points, If by chance you bought the AP with wrong Regulatory domain then you must change or replace this Access Point.

*** Here is the Wireless LAN Compliance Status

There are some Limitations for Multiple Country code configuration:

  • When the multiple-country feature is being used, all controllers that are going to join the same RF group must be configured with the same set of countries, configured in the same order.
  • When multiple countries are configured and the RRM auto-RF feature is enabled, the RRM assigns the channels that are derived by performing a union of the allowed channels per the AP country code. The APs are assigned channels by the RRM based on their PID country code. APs are only allowed to use legal frequencies that match their PID country code. Ensure that your AP’s country code is legal in the country that it is deployed.
  • The access point can only operate on the channels for the countries that they are designed for.
  • The country list configured on the RF group leader determines what channels the members would operate on. This list is independent of what countries have been configured on the RF group members.

Procedure to add Country Code on WLC:

 Via GUI:

Before Configuring / Changing the Country code on WLC, we must disable the both networks

Steps to disable the 802.11a and 802.11b/g networks:

Step1: Choose Wireless> 802.11a/n > Network.

Unselect the 802.11a Network Status check box.

802.11a_enable

Click Apply to commit your changes.

Step2: Choose Wireless > 802.11b/g/n > Network.

Unselect the 802.11b/g Network Status check box.

802.11b_enable

Click Apply to commit your changes.

Step3: Choose Wireless > Country, Select the check box for country where our access points are installed. If we selected more than one check box, a message appears indicating that RRM channels and power levels are limited to common channels and power levels.

Click ok

Here my all Access Points are in Europe domain and I am sitting in Germany so Choose DE(Germany).

Wirecountry

Step4: If we would have configured multiple country code on WLC then we could choose per AP for their country:

Here we chose only one Country so there is no other option for this AP.

AP_Country

Step5: Re-Enable the 802.11a and 802.11b/g networks (As we did in Step1 and Step2)

Step6: Click Save Configuration to save settings.

Via CLI:

Step1: Disable the 802.11a and 802.11b/g networks:

(WLAN1) >config 802.11a disable network
(WLAN1) >config 802.11b disable network

Step2: Configure the country codes for the countries where our access points are installed:

(WLAN1) >config country DE

*** If we choose multiple Country code on WLC then this will appear:

(WLAN1) >config country DE,US,MX
Changing country code could reset channel & RRM grouping configuration.
If running in RRM One-Time mode, reassign channels after this command.
Check customized APs for valid channel values after this command.
Are you sure you want to continue? (y/n) y
Configured Country............................. Multiple Countries:DE,MX,US
KEY: * = Channel is legal in this country and may be configured manually.
A = Channel is the Auto-RF default in this country.
. = Channel is not legal in this country.
C = Channel has been configured for use by Auto-RF.
x = Channel is available to be configured for use by Auto-RF.
(-,-) = (indoor, outdoor) regulatory doamin allowed by this country.

Step3: We can choose country per AP (If we configured multiple country cod eon WLC). In my example I configured only DE, so No need to assign to specific AP.

Choose Country for AP:

(WLAN1) >config ap country DE AP001

Step4: Re-Enable the 802.11a and 802.11b/g networks

(WLAN1) >config 802.11a enable network
(WLAN1) >config 802.11b enable network

Step5: Save settings:

(WLAN1) >save config

Step6: See the country code configured on WLC:

(WLAN1) >show country
Configured Country............................. DE  - Germany
Configured Country Codes
DE  - Germany................................... 802.11a Indoor,Outdoor / 802.11b / 802.11g

  1. Hi RSCCIEW,
    I have read your post and got a question for you… is there a way for us to know what channels the RRM is going to use when the controller supports multiple countries? I am reading that RRM would use common channels which are allowed in all the countries the WLC support. But, when it comes to reality, how can we see those channels that RRM is using?
