None
Description
Use the loopback-detection per-vlan enable command to configure the system to run loopback
detection on all VLANs of the current trunk or hybrid port.
Use the undo loopback-detection per-vlan enable command to restore the default setting.
By default, the system runs loopback detection only on the default VLAN of the trunk or hybrid port.
Note that, this command is not applicable to access ports. When the link type of a non-access port
changes to access, the loopback-detection per-vlan enable command already configured on the port
becomes invalid automatically.
