Precautions for configuring port isolation on S series switches

Precautions for configuring port isolation on S series switches (except the S1700) are as follows:
1. Port isolation takes effect only for interfaces on the same switch, and cannot take effect for interfaces on different switches.
2. Interfaces in a port isolation group are isolated from each other, but interfaces in different port isolation groups can communicate. If the group-id parameter is not specified, interfaces are added to port isolation group 1 by default.
3. For S series switches, the default port isolation mode is Layer 2 isolation and Layer 3 interworking. To configure Layer 2 and Layer 3 isolation, run the port-isolate mode all command in the system view.
