Views Ethernet interface view, aggregate interface view Predefined user roles network-admin Usage guidelines On a port, the loop guard function, the root guard function, and the edge port setting are mutually exclusive, and the one that is configured first takes effect. When the setting is configured in Ethernet interface view, it takes effect on only that interface. When the setting is configured in 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.
