4.1 Introduction to ARP Proxy
When one of the following things occurs, you have to enable the ARP proxy function, if
you want to realize layer 3 internetworking between ports.
The layer 2 isolation is realized between ports within the same VLAN (if several
ports in the same VLAN are added to the same isolation group, these ports cannot
visit each other).
The Super VLAN is enabled.
The isolate-user-vlan function is enabled on the connected layer 2 switch.
ARP proxy means that the ARP request sent from one host on a network to another
isolated port on the same network or a host on another network is forwarded by device
which connects the two networks and has the ARP proxy function, and thus realized the
layer 3 internetworking between layer 2 isolated-ports.
