Introduction to Port Isolation
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:
S7900E series Ethernet switches support only one isolation group that is created automatically by
the system as isolation group 1. These devices are referred to as single-isolation-group devices.
You can neither remove the isolation group nor create other isolation groups on such devices.
Layer 2 traffic can be exchanged between a port inside an isolation group and a port outside the
isolation group, but not between ports inside the isolation group.
There is no restriction on the number of ports assigned to an isolation group.

and all its member ports.
In port group view, the subsequent
configurations apply to all ports in the
port group.
