Usage guidelines
When port role restriction is enabled on a port, the port cannot become a root port.
If this command is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.
If this command is configured in Layer 2 aggregate interface view, it takes effect only on the
aggregate interface.
If this command is configured on a member port in an aggregation group, it takes effect only after the
port leaves the aggregation group.
