After completing preceding configurations, use the ping command to verify the connectivity between
Host A and Host D.
Local proxy ARP configuration example in case of port isolation
Network requirements
As shown in Figure 35, Host A and Host B belong to the same VLAN, and connect to Switch via Ethernet
1/3 and Ethernet 1/1 respectively. Switch connects to LB module via Ethernet 1/2.
Configure port isolation on Ethernet 1/3 and Ethernet 1/1 of Switch. Enable proxy ARP on LB module
to allow communication between Host A and Host B at Layer 3.
Figure 35 Network diagram for local proxy ARP between isolated ports
NOTE:
• The switch in this diagram is a distributed device.
• In this configuration example, all traffic between the hosts is blocked, so you need to configure local
proxy ARP on Ten-GigabitEthernet 0/0.1 of LB module to enable communication between Host A and
Host B. If the two ports (Ethernet 1/3 and Ethernet 1/1) on the switch are isolated only at Layer 2, you
can enable communication between the two hosts by configuring local proxy ARP on VLAN-interface 2
of the switch.
