F3215-HP Load Balancing Module Network Management Configuration Guide-6PW101

# Configure the IP address of interface GigabitEthernet 0/1.

[LB] interface gigabitethernet 0/1

[LB-GigabitEthernet0/1] ip address 192.168.20.99 255.255.255.0

# Enable proxy ARP on interface GigabitEthernet 0/1.

[LB-GigabitEthernet0/1] proxy-arp enable

[LB-GigabitEthernet0/1] quit

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 48, Host A and Host B belong to the same VLAN, and connect to the switch through

Ethernet 1/3 and Ethernet 1/1 respectively. The switch connects to LB through Ethernet 1/2.

Configure port isolation on Ethernet 1/3 and Ethernet 1/1 of the switch to isolate Host A from Host B at

Layer 2. Enable local proxy ARP on LB to allow communication between Host A and Host B at Layer 3.

In this configuration example, suppose all traffic between the hosts is blocked, so you need to configure

local proxy ARP on GigabitEthernet 0/2 of LB 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.

Configuration procedure

1. Configure the switch:

# Add Ethernet 1/3, Ethernet 1/1, and Ethernet 1/2 to VLAN 2. Configure port isolation for Host

A and Host B.
