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.

Examples

<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
