The following table describes the labels in this screen.
7.5.4 VLAN-Based Port Isolation
Port isolation allows each port to communicate only with the CPU management port but not
communicate with each other. All incoming ports are selected while only the CPU outgoing
port is selected. This option is the most limiting but also the most secure. With VLAN-based
port isolation, you can specify which ports (in a VLAN) are allowed to communicate with
which port(s).
Click Port Isolation in the VLAN Port Setting screen. Refer to Section 7.1 on page 79 for
background information.
