Introduction

The following information provides an example for configuring auto TPC.

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 TPC

Network configuration

As shown in Figure 1, each AP is enabled with only one radio. Configure auto-TPC and set the adjacency factor to 3 to enable the AC to perform auto TPC when AP 4 joins. Add radio 1 of AP 1 to an RRM holddown group to avoid frequent power 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.

3.     Click the More icon  in the upper right corner of the Radios for all APs area.

4.     Click the Edit icon  for AP 1 and then select OFF from the Power lock field.

5.     Repeat the previous steps to disable power lock for AP 2, AP 3, and AP 4.

Configuring auto TPC

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 TPC as follows:

¡     Enable auto TPC.

¡     Set the TPC mode to Custom.

¡     Set the maximum neighbor quantity, power adjustment threshold, and minimum transmit power to 3, 70, and 5, respectively.

¡     Retain the default settings for the other fields.

¡     Click Apply.

5.     Repeat the previous steps to configure auto TPC for AP 2, AP 3, and AP 4.

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

¡     Set the group ID to 10.

¡     Set the power holddown time to 100 minutes.

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

¡     Retain the default settings for the other fields.

¡     Click Apply.

Verifying the configuration

# Click the Network View tab at the bottom of the page and access the Monitoring > RF Monitoring page to view detailed information about channel adjustment. If auto TPC is configured correctly, the joining of AP 4 triggers the system to compare the third strongest radio RSSI with the power adjustment threshold. The system decreases or increases the transmit power of the radio if the RSSI is higher or lower than the threshold.

# Verify that the transmit power of radio 1 on AP 1 remains unchanged within 100 minutes after the first TPC.
