39.1.3 Setting Loopback Detection
39.1.3.1 Configuring Loopback Detection Globally
Enabling or disabling loopback detection globally means enabling or disabling loopback detection on all
physical ports. Global configuration is just like a switch. Only when this switch is opened can enabled
loopback detection on a port take effect.
Command Purpose
[no] loopback-detection
Sets loopback detection globally.
39.1.3.2 Configuring Port Loop Check
If you want to enable or disable loopback detection on a specified port, you should first enable loopback
detection globally.
Command Purpose
[no] loopback-detection enable
Configures port loopback detection.
39.1.3.3 Configuring a Port to Conduct Loopback Detection in Specified VLAN
If you set loopback detection in a specified VLAN, a port shall transmit multiple detection packets with
specified VLAN tag regularly and the port can transmit up to 10 detection packets with specified VLAN tag.
