Configuring AP Channel Assignments
The country code in the AP Regulatory Domain profile determines supported channel and channel pairs for
that specific AP. Any changes to the country code causes the valid channel lists to be reset to the defaults for
the country.
The example in this section illustrates how to perform the following tasks for an AP group:
1. Configure the “default” regulatory domain profile to use a valid country code. (In this example, the country
code US.) This will determine the available channels.
2. Configure a 40 MHz channel (bonded pair) for the AP group’s 802.11a (5 GHz) radio profile.
3. Configure a 20 MHz channel for the AP group’s 802.11g (2.4 GHz) radio profile.
This example uses default ARM profile settings and the recommended high-throughput channel assignments for the
802.11a and 802.11b/g bands. If you want the channel assignments to utilize high-throughput, ensure that high-
throughput is enabled within the radio profile. For details, see 802.11a and 802.11g RF Management Profiles on page
558.
Using the WebUI
1. Navigate to Configuration > Wireless > AP Configuration > AP Group page.
2. Click the Edit button by the name of the AP group to which you want to assign specific channels.
3. In the Profiles list, expand the AP menu to display the AP profiles used by the AP group.
4. Select the Regulatory Domain profile named default.
5. Click the Country Code drop-down menu and select the US-United States domain if it is not already
selected.
The Regulatory Domain’s country code determines which channels are selected in the following fields:
n Valid 802.11g channel
n Valid 802.11a channel
n Valid 802.11g 40MHz channel pair
n Valid 802.11a 40MHz channel pair
n Valid 802.11a 80MHz channel group
n Valid 802.11a 160MHz channel group
If none of the channels supported by the AP have received regulatory approval by the country whose
country code you selected, the AP will revert to Air Monitor mode.
6. In the Valid 802.11a 80MHz channel group field, define which 80MHz channels on the 802.11a band
are available for assignment by ARM and for the switch to randomly assign if user has not specified a
channel. The channel numbers below correspond to channel center frequency.
n Possible choices in US: 42, 58, 106, 122, 138, 155
n Possible choices in EU: 42, 58, 106, 122
n Possible choices in JP: 42, 58, 106, 122
n Possible global choices: 42, 58, 106, 122, 138, 155
7. Click Apply.
8. Under the Profiles list, expand the RF Management menu.
9. Select the 802.11a radio profile used by the AP group
10.Enter 36 in the Channel text field and select the Above radio button. In this instance, channel 36 becomes
the primary channel and the secondary channel is 40.
11.Click Apply.
12.Under the Profiles list select the 802.11g radio profile used by the AP group.
