Port isolation configuration example

Network requirements

As shown in Figure 436:

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.

Figure 436 Networking diagram

Configuring the switch

1.Assign ports GigabitEthernet 1/0/2, GigabitEthernet 1/0/3, and GigabitEthernet 1/0/4 to the isolation group:

a.Select Security > Port Isolate Group from the navigation tree.

b.Click the Port Setup tab.

c.Select Isolated port for Config Type.

d.Select 2, 3, 4 on the chassis front panel. 2, 3, 4 represent ports GigabitEthernet 1/0/2, GigabitEthernet 1/0/3, and GigabitEthernet 1/0/4, respectively.
