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, you can create only one isolation group on an S3100 Series Ethernet switch. The number of Ethernet ports in an isolation group is not limited.
& Note:
l An isolation group only isolates the member ports in it.
l Port isolation is independent of VLAN configuration.
1.2 Port Isolation Configuration
You can perform the following operations to add an Ethernet ports to an isolation group, thus isolating Layer 2 and Layer 3 data among the ports in the isolation group.

port isolate |
Required By default, an isolation group contains no port. |
& Note:
l When a member port of an aggregation group joins/leaves an isolation group, the other ports in the same aggregation group on the local device will join/leave the isolation group at the same time.
l For ports that belong to an aggregation group and an isolation group simultaneously, removing a port from the aggregation group has no effect on the other ports. That is, the rest ports remain in the aggregation group and the isolation group.
l Ports that belong to an aggregation group and an isolation group simultaneously are still isolated even when you remove the aggregation group in system view.
l Adding a port of an isolation group to an aggregation group causes all the ports in the aggregation group being added to the isolation group.
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.
