Which of the description about the port isolation of Huawei switch provides the function of configuring port isolation?

A. The port isolation mode can be configured as Layer 2 and Layer 3 isolation or Layer 2 isolation as Layer 3 interworking.

B. Huawei switches support 64 isolation groups, numbered 0~63.

C. Interface unidirectional isolation supports mixed isolation of four types of interfaces: E, GE, XGE, and Eth-Trunk. However, it does not support unidirectional isolation of an interface from itself, unidirectional isolation of an interface from a management network interface, and Eth-Trunk and its member interfaces. One-way isolation.

D. If it is isolated from interface B on interface A, the packets sent from interface A cannot reach interface B, but the packets sent from interface B can reach interface A.
