Issue Description
What Precautions Should Be Taken to Configure Port Isolation?
Solution
Port isolation applies only to interfaces of the same device and cannot isolate interfaces on different devices.

Interfaces in a port isolation group are isolated from each other, but interfaces in different port isolation groups can communicate. If group-id is not specified, an interface is added to port isolation group 1.

By default, port isolation blocks Layer 2 communication but allows Layer 3 communication. To isolate interfaces at both Layer 2 and Layer 3, run the port-isolate mode all command in the system view.
