Figure 7 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, and therefore you need to
configure local proxy ARP on GigabitEthernet 1/2 of the device to enable communication between Host
A and Host B. If the two ports (GigabitEthernet 1/3 and GigabitEthernet1/1) 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
Step1
Configure the switch
# Add GigabitEthernet 1/3, GigabitEthernet 1/1 and GigabitEthernet 1/2 to VLAN 2. Configure port
isolation on Host A and Host B.
[Switch] port-isolate group 2
[Switch] vlan 2
[Switch-vlan2] port gigabitethernet 1/3
[Switch-vlan2] port gigabitethernet 1/1
[Switch-vlan2] port gigabitethernet 1/2
[Switch-vlan2] quit
[Switch] interface gigabitethernet 1/3
[Switch-GigabitEthernet1/3] port-isolate enable group 2
[Switch-GigabitEthernet1/3] interface gigabitethernet 1/1
[Switch-GigabitEthernet1/1] port-isolate enable group 2
[Switch-GigabitEthernet1/1] interface gigabitethernet 1/2
[Switch-GigabitEthernet1/2] port-isolate uplink-port group 2
Step2
Configure the device
# Specify the IP address of GigabitEthernet 0/2.
[Device] interface gigabitethernet 0/2
[Device-GigabitEthernet0/2] ip address 192.168.10.100 255.255.0.0
