address in the same IP segment of the port but not the same physical network, if the port
has enabled proxy ARP, the port would reply to the ARP with its own MAC address and
forward the actual packets received. Enabling proxy ARP allows machines physically
separated but of the same IP segment ignores the physical separation and communicate
via proxy ARP interface as if in the same physical network.

ARP Configuration Task List
ARP Configuration Task List:
1. Configure static ARP
2. Configure proxy ARP
3. Clear dynamic ARP
4. Clear the statistic information of ARP messages
1. Configure static ARP
Command
Explanation
VLAN Interface Mode
arp <ip_address> <mac_address>
{interface [ethernet] <portName>}
no arp <ip_address>
Configures a static ARP entry; the no
command deletes a ARP entry of the
specified IP address.
2. Configure proxy ARP
Command
Explanation
VLAN Interface Mode
ip proxy-arp
no ip proxy-arp
Enables the proxy ARP function for
Ethernet ports: the no command disables
the proxy ARP.
3. Clear dynamic ARP
Command
Explanation
Admin mode
clear arp-cache
Clear the dynamic ARP learnt by the
switch.
4. Clear the statistic information of ARP message
Command
Explanation
Admin mode
