Prerequisites for Configuring Country Codes• Generally, you configure one country code per switch; you configure one code that matches the physicallocation of the switch and its access points. You can configure up to 20 country codes per switch. Thismultiple-country support enables you to manage access points in various countries from a single switch.

•When the multiple-country feature is used, all switchs that are going to join the same RF group must beconfigured with the same set of countries, configured in the same order.

• Access points are capable of using all the available legal frequencies. However, access points are assignedto the frequencies that are supported in their relevant domains.

• The country list configured on the RF group leader determines which channels the members wouldoperate on. This list is independent of which countries have been configured on the RF group members.

• For switchs in the Japan regulatory domain, you must have had one or more Japan country codes (JP,J2, or J3) configured on your switch at the time you last booted your switch.

• For switchs in the Japan regulatory domain, you must have at least one access point with a -J regulatorydomain joined to your switch.

Information About Configuring Country CodesControllers 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 forEurope), but the country code enables you to specify a particular country of operation (such as FR for Franceor ES for Spain). Configuring a country code ensures that each radio’s broadcast frequency bands, interfaces,channels, and transmit power levels are compliant with country-specific regulations.

Information About Migrating Access Points from the -J Regulatory Domain tothe -U Regulatory Domain

The Japanese government has changed its 5-GHz radio spectrum regulations. These regulations allow a textbox upgrade of 802.11a 5-GHz radios. Japan allows three frequency sets:

• J52 = 34 (5170 MHz), 38 (5190 MHz), 42 (5210 MHz), 46 (5230 MHz)

•W52 = 36 (5180 MHz), 40 (5200 MHz), 44 (5220 MHz), 48 (5240 MHz)

•W53 = 52 (5260 MHz), 56 (5280 MHz), 60 (5300 MHz), 64 (5320 MHz)

Cisco has organized these frequency sets into the following regulatory domains:

• -J regulatory domain = J52

• -P regulatory domain = W52 + W53

• -U regulatory domain = W52

Regulatory domains are used by Cisco to organize the legal frequencies of the world into logical groups. Forexample, most of the European countries are included in the -E regulatory domain. Cisco access points areconfigured for a specific regulatory domain at the factory and, with the exception of this migration process,never change. The regulatory domain is assigned per radio, so an access point’s 802.11a and 802.11b/g radioscan be assigned to different domains.

Switchs and access points might not operate properly if they are not designed for use in your country ofoperation. For example, an access point with part number AIR-CAP3602I-A-K9 (which is included in theAmericas regulatory domain) cannot be used in Australia. Always be sure to purchase switchs and accesspoints that match your country’s regulatory domain.

Note

The Japanese regulations allow the regulatory domain that is programmed into an access point’s radio to bemigrated from the -J domain to the -U domain. New access points for the Japanese market contain radios thatare configured for the -P regulatory domain. -J radios are no longer being sold. In order to make sure thatyour existing -J radios work with the new -P radios in one network, you need to migrate your -J radios to the-U domain.

Country codes define the channels that can be used legally in each country. These country codes are availablefor Japan:

Configuring Country CodesInformation About Configuring Country Codes

• JP—Allows only -J radios to join the controller

• J2—Allows only -P radios to join the controller

• J3—Uses the -U frequencies but allows both -U and -P radios to join the controller

• J4—Allows 2.4G PQU and 5G JPQU to join the controller

See the Channels and Maximum Power Settings for Cisco Aironet Lightweight Access Points document forthe list of channels and power levels supported by access points in the Japanese regulatory domains.

Using the W56 Band in JapanThe Japanese government is formally permitting wireless LAN use of the frequencies in the W56 band for802.11a radios. The W56 band includes the following channels, frequencies, and power levels (in dBm):

15175680136

15175700140

To set up a network consisting of only -P and -Q access points, configure the country code to J2. To set up anetwork that consists of -P, -Q, and -U access points, configure the country code to J3.

Dynamic Frequency SelectionThe Cisco converged access solution complies with regulations that require radio devices to use DFS to detectradar signals and avoid interfering with them.

Configuring Country CodesUsing the W56 Band in Japan

When a lightweight access point with a 5-GHz radio operates on one of the 15 channels listed in the tablebelow, the switch to which the access point is associated, automatically uses DFS to set the operating frequency.

When you manually select a channel for DFS-enabled 5-GHz radios, the controller checks for radar activityon the channel for 60 seconds. If there is no radar activity, the access point operates on the channel that youselected. If there is radar activity on the channel that you selected, the controller automatically selects adifferent channel, and after 30 minutes, the access point retries the channel.

After radar has been detected on a DFS-enabled channel, it cannot be used for 30 minutes.Note

The Rogue Location Detection Protocol (RLDP) and rogue containment are not supported on the channelslisted in the table below.

Note

The maximum legal transmit power is greater for some 5-GHz channels than for others. When the switchrandomly selects a 5-GHz channel on which power is restricted, it automatically reduces the transmitpower to comply with power limits for that channel.

Note

Table 1: DFS-Enabled 5-GHz Channels

124 (5620 MHz)104 (5520 MHz)52 (5260 MHz)

128 (5640 MHz)108 (5540 MHz)56 (5280 MHz)

132 (5660 MHz)112 (5560 MHz)60 (5300 MHz)

136 (5680 MHz)116 (5580 MHz)64 (5320 MHz)

140 (5700 MHz)120 (5600 MHz)100 (5500 MHz)

Using DFS, the controller monitors operating frequencies for radar signals. If it detects radar signals on achannel, the controller takes these steps:

• It changes the access point channel to a channel that has not shown radar activity within the last 30minutes. (The radar event is cleared after 30 minutes.) The controller selects the channel at random.

• If the channel selected is one of the channels in the UNII-2 or UNII-2e that is affected by DFS, it scansthe new channel for radar signals for 60 seconds. If there are no radar signals on the new channel, theswitch accepts client associations.

• It records the channel that showed radar activity as a radar channel and prevents activity on that channelfor 30 minutes.

• It generates a trap to alert the network manager.
