Command Changes
The following table summarises the new commands:
Preventing MAC Address Resolution Between Hosts
Within a Subnet
A new feature lets you stop MAC address resolution between hosts within an
interface’s subnet. Local proxy ARP ensures that devices within a subnet
cannot send traffic that bypasses the router or switch. This lets you monitor,
filter, and control traffic between devices in the same subnet.
Local proxy ARP extends proxy ARP by intercepting and responding to ARP
requests between hosts within a subnet. It responds to the ARP requests with
the router or switch’s own MAC address details instead of those from the
destination host. This stops hosts from learning the MAC address of other
hosts within its subnet.
When local proxy ARP is operating on an interface, the router or switch does
not generate or forward any ICMP-Redirect messages on that interface.
To create an interface that uses local proxy ARP, use the command:
add ip interface=interface ipaddress={ipadd|dhcp}
proxyarp=local [other-options]
To change an interface to use local proxy ARP, use the command:
set ip interface=interface ipaddress={ipadd|dhcp}
proxyarp=local [other-options]
