Configuring Static ARP Entries
ARP dynamically maps the MAC and IP addresses, and while most network host support dynamic mapping, you can configure an ARP
entry (called a static ARP) for the ARP cache.
To configure a static ARP entry, use the following command.
•
Configure an IP address and MAC address mapping for an interface.
CONFIGURATION mode
arp vrf
vrf-name
ip-address mac-address interface
•
vrf
vrf-name
: use the VRF option to configure a static ARP on that particular VRF.
•
ip-address
: IP address in dotted decimal format (A.B.C.D).
•
mac-address
: MAC address in nnnn.nnnn.nnnn format.
•
interface
: enter the interface type slot/port information.
Example of the
show arp
Command
These entries do not age and can only be removed manually. To remove a static ARP entry, use the
no arp ip-address
command.
To view the static entries in the ARP cache, use the
show arp static
command in EXEC privilege mode.

no proxy-arp
command in the interface mode.
To re-enable Proxy ARP, use the following command.
•
Re-enable Proxy ARP.
INTERFACE mode
ip proxy-arp
To view if Proxy ARP is enabled on the interface, use the
show config
command in INTERFACE mode. If it is not listed in the
show
config
command output, it is enabled. Only non-default information is displayed in the
show config
command output.
