196 CHAPTER 24: PORT ISOLATION CONFIGURATION
n
■ 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.

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.
