Local Proxy ARP Configuration in Port Isolation Application
Network requirements
z
Switch A (a S3600 series Ethernet switch) is connected to Switch B through Ethernet 1/0/1.
z
Ethernet 1/0/2 and Ethernet 1/0/3 on Switch B belong to VLAN 1, and are connected to Host A and
Host B respectively.
z
Host A and Host B isolated at Layer 2 can communicate at Layer 3 through Switch A.

Configuration procedure
1) Configure Switch B
# Add Ethernet 1/0/2 and Ethernet 1/0/3 into an isolation group, disabling Host A and Host B from
communicating with each other at Layer 2.
For details about port isolation, refer to the part discussing port isolation.
