Port isolation configuration example
Network requirements
As shown in Figure 14:
 Hosts A, B, and C are connected to port GigabitEthernet 1/0/1, GigabitEthernet 1/0/2, and
GigabitEthernet 1/0/3 of Device.
 Device is connected to the Internet through GigabitEthernet 1/0/4.
 GigabitEthernet 1/0/1, GigabitEthernet 1/0/2, GigabitEthernet 1/0/3, and GigabitEthernet
1/0/4 belong to the same VLAN.
Configure Device to enable Host A, Host B, and Host C to access the Internet when they are isolated from
one another.
