Chapter 1 Port Isolation Configuration
1.1 Port Isolation Overview
Through the port isolation feature, you can add the ports to be controlled into an isolation group to isolate the Layer 2 and Layer 3 data between each port in the isolation group. Thus, you can construct your network in a more flexible way and improve your network security.
Currently, an S3100-52P Ethernet Switch supports only one isolation group, but does not limit the number of Ethernet ports in the unique isolation group.
& Note:
Port isolation is independent of VLAN configuration.
1.2 Port Isolation Configuration
You can perform the following operations to add individual Ethernet ports to the isolation group, thus isolating Layer 2 and Layer 3 data between each port in the isolation group.

port isolate |
Required By default, an isolation group contains no port. |
& Note:
When the port isolate command or the undo port isolate command is executed on a member port of an aggregation group, the other ports in the same aggregation group on the local device will be added to or removed from the isolation group together at the same time.
1.3 Displaying Port Isolation Configuration
After the above configuration, you can execute the display command in any view to display the result of your port isolation configuration, thus verifying your configuration.

1.4 Port Isolation Configuration Example
I. Network requirements
l PC2, PC3 and PC4 connect to the switch ports Ethernet1/0/2, Ethernet1/0/3, and Ethernet1/0/4 respectively.
l The switch connects to the Internet through Ethernet1/0/1.
l It is desired that PC2, PC3 and PC4 are isolated from each other so that they cannot communicate with each other.
