Configuring port isolation

Port isolation enables isolating Layer 2 traffic for data privacy and security without using VLANs. You
can also use this feature to isolate the hosts in a VLAN from one another.
To use the feature, assign ports to a port isolation group. Ports in an isolation group are called
"isolated ports." One isolated port cannot forward Layer 2 traffic to any other isolated port on the
same switch, even if they are in the same VLAN. An isolated port can communicate with any port
outside the isolation group if they are in the same VLAN.
The switch series supports only one isolation group "isolation group 1." The isolation group is
automatically created and cannot be deleted. There is no limit on the number of member ports.
