Root Guard
(Standalone
mode)
Select this check box to enable root guard on this port in order to prevent the switch(es)
attached to the port from becoming the root bridge.
With root guard enabled, a port is blocked when the Switch receives a superior BPDU on
it. The Switch allows traffic to pass through this port again when the switch connected to
the port stops to send superior BPDUs.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses
these changes if it is turned off or loses power, so use the Save link on the top navigation
panel to save your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
