Impact on communication
If an interface that is up is changed by using this command, it first goes down and then
comes up again.
Accordingly, the following might occur:
 If communication is in progress on the applicable interface, it stops.
 Dynamic ARP entries generated for the applicable interface are deleted.
When the change is applied
The change is applied immediately after setting values are changed.
