Usage guidelines

When port role restriction is enabled on a port, the port cannot become a root port.

When the command is configured in Layer 2 Ethernet interface view, it takes effect only on that interface.

When the command is configured in Layer 2 aggregate interface view, it takes effect only on the aggregate interface.

When the command 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.

<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] stp role-restriction
