Configuring port isolation
Overview
Usually, Layer 2 traffic isolation is achieved by assigning ports to different VLANs. To save VLAN
resources, port isolation isolates ports within a VLAN, allowing for great flexibility and security.
The device supports multiple isolation groups that can be configured manually.
There is no restriction on the number of ports assigned to an isolation group.
Layer 2 traffic cannot be forwarded between ports in different VLANs. Within the same VLAN, ports in
an isolation group can communicate with those outside the isolation group at Layer 2.
