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.
HP V1910 Switch Series supports 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 from different VLANs. However, Layer 2 data
transmission between ports within and outside the isolation group is supported.
