IP Addressing and Protocol Commands

ip local-proxy-arp

This command allows you to stop MAC address resolution between hosts within a private
VLAN edge interface. Local Proxy ARP works by intercepting ARP requests between hosts
within a subnet and responding with your device's own MAC address details instead of the
destination host's details. This stops hosts from learning the MAC address of other hosts within
its subnet through ARP requests.
Local Proxy ARP ensures that devices within a subnet cannot send traffic that bypasses layer 3
routing on your device. This lets you monitor and filter traffic between hosts in the same
subnet, and enables you to have control over which hosts may communicate with one another.
When Local Proxy ARP is operating on an interface, your device does not generate or forward
any ICMP-Redirect messages on that interface. This command does not enable proxy ARP on
the interface; see the
The no form disables Local Proxy ARP to stop your device from intercepting and responding
to ARP requests between hosts within a subnet. This allows the hosts to use MAC address
resolution to communicate directly with one another. Local Proxy ARP is disabled by default.
