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.
Examples
# Enable the loop guard function on GigabitEthernet 3/0/1.
<Sysname> system-view
[Sysname] interface GigabitEthernet 3/0/1
[Sysname-GigabitEthernet3/0/1] stp loop-protection
