Usage guidelines

On a port, the loop guard feature and the root guard feature are mutually exclusive.

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

# Enable root guard on Ten-GigabitEthernet 1/0/1.

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