Port This field displays the port number. In Stacking mode, the first number represents the slot ID and
the second is the port number. Please note that the default stacking ports (the last four ports of
your Switch) cannot be configured. They are reserved for stacking only.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set
the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Active Select this check box to enable the BPDU guard feature on this port. The Switch shuts down this
port if there is any BPDU received on the port.
Clear this check box to disable the BPDU guard feature.
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.
