Caution:
z Static ARP mapping entries are valid as long as the Ethernet switch operates. But
the following operations result in ARP entries being removed: changing/removing
a VLAN interface, removing a VLAN, or removing a port from a VLAN.
z As for the arp static command, the value of the vlan-id argument must be the ID of
an existing VLAN, and the port identified by the interface-type and
interface-number arguments must belong to the VLAN.
z Currently, the system does not support static ARP mapping entry at aggregation
port.
