Description
Use the arp static command to configure ARP mapping table.
Use the undo arp command to delete mapping items corresponding to some
addresses in the ARP mapping table.
By default, the mapping table of the system ARP is empty and the address mapping
can be obtained through dynamic ARP.
Normally, ARP mapping table is maintained by dynamic ARP, only in special
circumstances is manual configuration needed. Besides, ARP mapping table is used
for LAN only, WAN address resolution is accomplished in a different way, for instance
the inverse address resolution of Frame Relay.
