Port Isolation Configuration Example

Network requirements
Users Host A, Host B, and Host C are connected to 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, GigabitEthernet1/0/3 and GigabitEthernet1/0/4
belong to the same VLAN. It is desired that Host A, Host B, and Host C cannot communicate with
one another at Layer 2, but can access the Internet.
