Introduction

The following information provides an example for configuring auto DFS.

Prerequisites

The following information applies to Comware 7-based access controllers. Procedures and information in the examples might be slightly different depending on the software or hardware version of the H3C access controllers.

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of WLAN configuration.

Example: Configuring auto DFS

Network configuration

As shown in Figure 1, configure auto-DFS for the system to adjust radio channels when a channel adjustment trigger condition is met. Add radio 1 of AP 1 to an RRM holddown group to avoid frequent channel adjustments.

Procedures

Configuring basic AC settings

Configure wireless service, IP address, AP access, and radio settings on the AC. (Details not shown.)

Configuring channel settings

1.     Click the Network View tab at the bottom of the page.

2.     From the navigation pane, select Wireless Configuration > Radio Management.

5.     Repeat the previous steps to enable auto channel selection for AP 2 and AP 3.

Configuring auto DFS

1.     From the navigation pane, select Wireless Configuration > Radio Management.

2.     Click the RRM tab.

3.     Click the More icon  in the upper right corner of the AP configuration area.

4.     Click the Edit icon  for AP 1 and configure auto DFS as follows:

¡     Enable auto DFS.

¡     Set the DFS sensitivity to Custom.

¡     Set the CRC error threshold, interference threshold, and tolerance level to 30, 60, and 25, respectively.

¡     Retain the default settings for the other fields.

¡     Click Apply.

5.     Repeat the previous steps to configure auto DFS for AP 2 and AP 3.

6.     Click the RRM Holddown Group tab, click the Add icon , and then configure an RRM holddown group as follows:

¡     Set the group ID to 10.

¡     Set the channel holddown time to 600 minutes.

¡     Add radio 1 of AP 1 as a group member.

¡     Retain the default settings for the other fields.

¡     Click Apply.

Verifying the configuration

# Verify that the radios' working channels change when a channel adjustment trigger condition is met and the calibration interval is reached. You can click the Network View tab and access the Monitoring > RF Monitoring page to view detailed information about channel adjustment.

# Verify that the channel for radio 1 on AP 1 remains unchanged within 600 minutes after the first DFS.
