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:
Switch 4510G Family 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.
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.
