Usage guidelines
When port role restriction is enabled on a port, the port cannot become a root port.
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 port role restriction on interface Ten-GigabitEthernet 1/0/1.
