You can configure and query the port isolation mode, bidirectional isolation, and unidirectional isolation. The S2300SI switches do not support this function.
If you want to prevent members in a group from communicating with each other but allow them to access the public devices, such as the printer and the server, you can set the port isolation mode to isolation at both Layer 2 and Layer 3 or Layer 2 isolation and Layer 3 communication.
