Operation Manual – Port IsolationH3C S3100 Series Ethernet Switches Chapter 1 Port Isolation Configuration1-2Note:z When a member port of an aggregation group joins/leaves an isolation group, theother ports in the same aggregation group on the local device will join/leave theisolation 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 arestill 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 inthe aggregation group being added to the isolation group.1.3 Displaying Port Isolation ConfigurationAfter the above configuration, you can execute the display command in any view todisplay the result of your port isolation configuration, thus verifying your configuration.Table 1-2 Display port isolation configurationOperation Command DescriptionDisplay information aboutthe Ethernet ports added tothe isolation groupdisplay isolate portYou can execute thedisplay command in anyview.1.4 Port Isolation Configuration ExampleI. Network requirementsz PC2, PC3 and PC4 connect to the switch ports Ethernet1/0/2, Ethernet1/0/3, andEthernet1/0/4 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 theycannot communicate with each other.
