Description
Use the stp loop-protection command to enable the loop guard function on the port(s).
Use the undo stp loop-protection command to restore the system default.
By default, the loop guard function is disabled.
Note that:
z 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 a
member port in an aggregation group, the setting can take effect only after the port leaves the
aggregation group.
z 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 root-protection.
Examples
