Click Apply to save the changes in this part of the screen to the system's volatile
memory. The system loses these changes if it is turned off or loses power, so use

need to manually enable the port in the Port Setup screen.
If you select dynamic, the system shuts down the port if the system detects that
packets sent out on the port loop back to the system. The port becomes active
automatically after the time you specified in the Time field.
Enter the time (in seconds) a port in dynamic mode waits to become active again
after shut down by the system.
