switches to register necessary VLAN members on ports across the network.

Select this check box to permit VLAN groups beyond the local switch.

Port Isolation Port Isolation allows each port (1 to 26) 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.
