An Ethernet port belongs to only one port isolation group. If you add an
■
Ethernet port to different isolation groups, the port belongs to only the latest
isolation group to which the port is added.
Currently, modules of Type A (3C16860, 3C16861, LS81FS24A, 3C16858, and
■
3C16859) do not support the Port Isolation feature.
After the above configuration, you can execute the display command in any view
to view the information about the Ethernet ports added to an isolation group.

Network requirements
PC2, PC3 and PC4 connect to the switch ports Ethernet2/0/2, Ethernet2/0/3,
■
and Ethernet2/0/4 respectively.
It is desired that PC2, PC3 and PC4 are isolated from each other so that they
■
cannot communicate with each other.
