Mdi - HP 6125G Command Reference Manual

Description
Use loopback-detection per-vlan enable to enable loopback detection in each VLAN on trunk or hybrid
ports.
Use undo loopback-detection per-vlan enable to disable loopback detection in all but the PVID on trunk
or hybrid ports.
By default, a trunk port or hybrid port performs loopback detection only in its PVID.
The loopback-detection per-vlan enable command is not applicable to access ports.
Examples
# Enable loopback detection in all VLANs on hybrid port GigabitEthernet 1/0/1.
<Sysname> system-view
