Usage guidelines
On a port, the loop guard function is mutually exclusive with the root guard function or the edge port
setting.
When the setting is configured in Layer 2 Ethernet interface view, it takes effect on only that interface.
When the setting is configured in Layer 2 aggregate interface view, it takes effect on only the aggregate
interface.
When the setting is configured on a member port in an aggregation group, it takes effect only after the
port leaves the aggregation group.

# Enable the loop guard function on Ten-GigabitEthernet 1/0/1.

[Sysname] interface ten-gigabitethernet 1/0/1
