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 improve the network security and network in a more
flexible way.
Currently, you can configure only one isolation group on a switch. The number of
Ethernet ports an isolation group can accommodate is not limited.
Note:
The port isolation function is independent of VLAN configuration.
