Parameter

None

Description

Use the loopback-detectionper-vlan enable command to configure the system to perform loopback detection on all VLANs on Trunk and Hybrid ports. Use the undo loopback-detectionper-vlan enable command to configure the system to only perform loopback detection on the default VLANs on the port.

By default, the system performs loopback detection to the default VLAN on Trunk and Hybrid ports.

Example

Configure the detection interval for the external loopback condition of each port to 10 seconds.
