Operation Manual – Port Isolation
H3C S3100 Series Ethernet Switches Chapter 1 Port Isolation Configuration
1-2
 Note:
z 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.
z 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.
z 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.
z 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.
1.3 Displaying Port Isolation Configuration
After the above configuration, you can execute the display command in any view to
display the result of your port isolation configuration, thus verifying your configuration.

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