Port Isolation Configuration Example - HP 1920 Gigabit Ethernet Switch Series User Manual

Port isolation configuration example

Network requirements
As shown in
Campus network users Host A, Host B, and Host C are connected to GigabitEthernet 1/0/2,
•
GigabitEthernet 1/0/3, and GigabitEthernet 1/0/4 of Switch.
Switch is connected to the external network through GigabitEthernet 1/0/1.
•
• GigabitEthernet 1/0/1, GigabitEthernet 1/0/2, GigabitEthernet 1/0/3, and GigabitEthernet
1/0/4 belong to the same VLAN.
Configure Host A, Host B, and Host C so that they can access the external network but are isolated from
one another at Layer 2.
