1.1.4 ARP Implementation Procedure

The ARP mapping table of a host is empty when the host is just started up. And when a
dynamic ARP mapping entry is not in use for a specified period of time, it is removed
from the ARP mapping table so as to save the memory space and shorten the interval
for the switch to look up entries in the ARP mapping table. For details, refer to Figure
1-3.
