Default Level

Parameters
None
Description
Use the stp root-protection command to enable the root guard function on the port(s).
Use the undo stp root-protection command to restore the default.
By default, the root guard function is disabled.
Note that:
Configured in Layer 2 Ethernet port view, the setting takes effect on the current port only;
configured in port group view, the setting takes effect on all ports in the port group; configured in
Layer 2 aggregate port view, the setting takes effect only on the aggregate port; configured on the
member port in an aggregation group, the setting can take effect only after the port leaves the
aggregation group.
Among loop guard, root guard and edge port settings, only one function (whichever is configured
the earliest) can take effect on a port at the same time.
Related commands: stp edged-port, stp loop-protection.
