Administration > LBD

The switch can be configured to detect general loopback conditions caused by hardware problems or faulty protocol settings. When enabled, a control frame is transmitted on the participating ports, and the switch monitors inbound traffic to see if the frame is looped back.

Usage Guidelines

Configuring Global Settings for LBD

Use the Administration > LBD (Configure Global) page to enable loopback detection globally, specify the interval at which to transmit control frames, the interval to wait before releasing an interface from shutdown state, the response to detectd loopback, and traps to send.

Configuring LBD Interface Settings

Use the Administration > LBD (Configure Interface) page to enable loopback detection on an interface, to display the loopback operational state, and the VLANs which are looped back.
