Add a static ARP
entry manually
arp static ip-address
mac-address [ vlan-id
interface-type
interface-number ]
Required
By default, there is no static ARP
entry in the ARP table, and ARP
entries are dynamically created by
ARP.
Caution:
z 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.
z 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.
