DESCRIPTION
Use this row to make the setting the same for all ports. Use this row first 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.
Select this check box to enable the loop guard feature on this port. The Switch sends
probe packets from this port to check if the Switch it is connected to is in loop state.
If the Switch that this port is connected is in loop state the Switch will shut down this
port.
Clear this check box to disable the loop guard feature.
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.
Click Cancel to begin configuring this screen afresh.
