Port Isolation Configuration
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.
An isolation group only isolates the member ports in it.
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.
