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 a Switch 4210. The number of Ethernet ports in an
isolation group is not limited.
An isolation group only isolates the member ports in it.
