IP LOCAL PROXY ARP

ip local-proxy-arp

Overview This command allows you to stop MAC address resolution between hosts within a
subnet. 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 is used in private VLAN edge (protected port) configurations.
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
information on enabling proxy ARP.
The no variant of this command 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.
