NOTE
After interface A is isolated from interface B unidirectionally, packets sent by interface A cannot reach
interface B, whereas packets sent from interface B can reach interface A.
NOTE
Ports in a port isolation group are isolated from each other, and ports in different port isolation groups can
communicate with each other. If group-id is not specified, a port is added to port isolation group 1.
