Use stp loop-protection to enable the loop guard function on the ports.

Use undo stp loop-protection to restore the default.

By default, the loop guard function is disabled.

Configured in Ethernet interface view, the setting takes effect only on the interface.

Configured in port group view, the setting takes effect on all ports in the port group.

Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate interface.

Configured on a member port in an aggregation group, the setting takes effect only after the port leaves the aggregation group.

You cannot configure edge port settings and loop guard, or configure root guard and loop guard on a port at the same time.
