Loopback Detection Configuration

6.1  Using the GUI

To avoid broadcast storm, we recommend that you enable storm control before loopback 

detection is enabled. For detailed introductions about storm control, refer to 

Configuring 

QoS

.

Choose the menu 

Switching > Port > Loopback Detection

 to load the following page.

Figure 6-1 

Loopback Detection

Follow these steps to configure loopback detection:
1)  In the 

Global Config

 section, enable loopback detection and configure the global 

parameters. Then click 

Apply

.

Loopback 

Detection Status

Enable loopback detection globally.

Detection 

Interval

Set the interval of sending loopback detection packets. 

The valid values are from 1 to 1000 seconds and the default value is 30 seconds.
