Displaying Port Isolation Configuration; Port Isolation Configuration Example - 3Com 4210 9-Port Configuration Manual

When a member port of an aggregation group joins/leaves an isolation group, the other ports in the
same aggregation group on the local device will join/leave the isolation group at the same time.
For ports that belong to an aggregation group and an isolation group simultaneously, removing a
port from the aggregation group has no effect on the other ports. That is, the rest ports remain in
the aggregation group and the isolation group.
Ports that belong to an aggregation group and an isolation group simultaneously are still isolated
even when you remove the aggregation group in system view.
Adding a port of an isolation group to an aggregation group causes all the ports in the aggregation
group being added to the isolation group.

Port Isolation Configuration Example

Network requirements
PC2, PC3 and PC4 connect to the switch ports Ethernet1/0/2, Ethernet1/0/3, and Ethernet1/0/4
respectively.
The switch connects to the Internet through Ethernet1/0/1.
It is desired that PC2, PC3 and PC4 are isolated from each other so that they cannot communicate
with each other.
