Chapter 7 Controlling Lightweight Access Points

Configuring Flashing LEDs

The Power Type/Mode field shows “degraded mode” if the access point is not operating at full power.

•To view the controller’s trap log, enter this command: show traplog

If the access point is not operating at full power, the trap contains “PoE Status: degraded operation.”

Configuring Flashing LEDs

Controller software release 4.0 or later enables you to flash the LEDs on an access point in order to locate it. All IOS lightweight access points support this feature.

Use these commands to configure LED flashing from the Privileged Exec mode of the controller.

Note The output of these commands is sent only to the controller console, regardless of whether the commands were issued on the console or in a TELNET/SSH CLI session.

1.To enable the controller to send commands to the access point from its CLI, enter this command: debug ap enable Cisco_AP

2.To cause a specific access point to flash its LEDs for a specified number of seconds, enter this command:

debug ap command “led flash seconds” Cisco_AP

You can enter a value between 1 and 3600 seconds for the seconds parameter.

3.To disable LED flashing for a specific access point, enter this command: debug ap command “led flash disable” Cisco_AP

This command disables LED flashing immediately. For example, if you run the previous command (with the seconds parameter set to 60 seconds) and then disable LED flashing after only 20 seconds, the access point’s LEDs stop flashing immediately.

Viewing Clients

You can use the controller GUI or CLI to view information about the clients that are associated to the controller’s access points.

Using the GUI to View Clients

Using the GUI, follow these steps to view client information.

Step 1 Click Monitor > Clients to open the Clients page (see Figure 7-27).
