Chapter 2 Port Isolation Function Configuration
2.1 Introduction to Port Isolation Function
Port isolation is an independent port-based function working in an inter-port way, which
isolates flows of different ports from each other. With the help of port isolation, users can
isolate ports within a VLAN to save VLAN resources and enhance network security. After this
function is configured, the ports in a port isolation group will be isolated from each other, while
ports belonging to different isolation groups or no such group can forward data to one another
normally. No more than 16 port isolation groups can a switch have.
2.2 Task Sequence of Port Isolation
1. Create an isolate port group
2. Add Ethernet ports into the group
3. Specify the flow to be isolated
4. Display the configuration of port isolation
1. Create an isolate port group
Command
Explanation
Global Mode
