Enter the parameters:

• Interface—An IPv4 interface can be configured on a port, LAG or VLAN. Select the
desired interface from the list of configured IPv4 interfaces on the device.
• IP Address—Enter the IP address of the local device.
• MAC Address—Enter the MAC address of the local device.
Click Apply. The ARP entry is saved to the Running Configuration file.
ARP Proxy
The Proxy ARP technique is used by the device on a given IP subnet to answer ARP queries
for a network address that is not on that network.
The ARP proxy feature is only available when the device is in L3 mode.
The ARP Proxy is aware of the destination of traffic, and offers another MAC address in reply.
Serving as an ARP Proxy for another host effectively directs LAN traffic destination to the
host. The captured traffic is then typically routed by the Proxy to the intended destination by
using another interface, or by using a tunnel.
The process in which an ARP-query-request for a different IP address, for proxy purposes,
results in the node responding with its own MAC address is sometimes referred to as
publishing.
To enable ARP Proxy on all IP interfaces:
Click IP Configuration > IPv4 Management and Interfaces > ARP Proxy.
Select ARP Proxy to enable the device to respond to ARP requests for remotely-located nodes
with the device MAC address.
Click Apply. The ARP proxy is enabled, and the Running Configuration file is updated.
