Port Isolation Group Configuration

Overview
Usually, Layer 2 traffic isolation is achieved by assigning ports to different VLANs. To save VLAN
resources, port isolation is introduced to isolate ports within a VLAN, allowing for great flexibility and
security.
Currently:
3Com Switch 2900 series support only one isolation group that is created automatically by the
system as isolation group 1. You can neither remove the isolation group nor create other isolation
groups on such devices.
There is no restriction on the number of ports assigned to an isolation group.
Usually, Layer 2 traffic cannot be forwarded between ports in different VLANs. However, the Layer 2
data transmission between ports within and outside the isolation group is supported.
