CAUTION:
Static ARP entries are valid as long as the Ethernet switch operates normally,
■
unless they are removed as the results of some operations, like
changing/removing a VLAN interface, removing a VLAN, and removing a port
from a VLAN.
The VLAN specified by the vlan-id argument in the arp static command must
■
be an existing VLAN, and the port specified by the interface-type and
interface-number arguments must belong to the VLAN.
