Local proxy ARP configuration example in case of port isolation Network requirements As shown in Figure 9, Host A and Host B belong to the same VLAN, and connect to Switch B via GigabitEthernet 1/0/3 and GigabitEthernet 1/0/1 respectively. Switch B connects to Switch A via GigabitEthernet 1/0/2. Configure port isolation on GigabitEthernet 1/0/3 and GigabitEthernet 1/0/1 of Switch B to isolate Host A from Host B at Layer 2. Enable local proxy ARP on Switch A to allow communication between Host A and Host B at Layer 3.
