Add a static ARP
mapping entry
manually
arp static ip-address
mac-address [ vlan-id
interface-type
interface-number ]
Required
The ARP mapping table is
empty when a switch is just
started. And the address
mapping entries are created
by ARP.
Caution:
z Static ARP mapping entries are valid as long as the Ethernet switch operates. But
operations that invalidate ARP entries, such as changing/removing VLAN interfaces,
removing VLANs, or removing ports from VLANs, may cause the corresponding
ARP entries being removed automatically.
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.
