NOTE:
•
Usually ARP dynamically generates ARP entries without manual intervention.
• To allow communication with a host by using a fixed IP-to-MAC mapping, configure a short static ARP
entry for it. To allow communication with a host through a specific interface in a specific VLAN by using
a fixed IP-to-MAC mapping, configure a long static ARP entry for it.
Configuring ARP
Configuring a static ARP entry
A static ARP entry is effective when the device it corresponds to works normally. However, when a VLAN
or VLAN interface is deleted, any static ARP entry corresponding to it will also be deleted (if it is a long
static ARP entry) or will become unresolved (if it is a short and resolved static ARP entry).
Follow these steps to configure a static ARP entry:

Configure
a static
ARP entry
Configure a long static ARP
entry
arp static ip-address mac-address
vlan-id interface-type
interface-number
Required
Use either command.
Not configured by
default.
Configure a short static
ARP entry
arp static ip-address mac-address
CAUTION:
•
The vlan-id argument must be the ID of an existing VLAN where the ARP entry resides. The specified
Ethernet interface must belong to that VLAN. The VLAN interface of the VLAN must be created.
• The IP address of the VLAN interface of the VLAN specified by the vlan-id argument must belong to the
same subnet as the IP address specified by the ip-address argument.
Configuring the maximum number of dynamic ARP entries for
an interface
Follow these steps to set the maximum number of dynamic ARP entries that an interface can learn:
