Description
Use the
stp loop-protection
command to enable the loop guard function on the port(s).
Use the
undo stp loop-protection
command to restore the system default.
By default, the loop guard function is disabled.
Configured in Layer 2 Ethernet interface view, the setting takes effect on the current interface only.
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.
Among loop guard, root guard and edge port settings, only one function (whichever is configured the
earliest) takes effect on a port at the same time.
