Abstract: This application discloses an information notification method and a related apparatus. The Ethernet storage system includes a first switching device and a first node, and the first switching device is an access device of the first node. The first node sends a join message to the first switching device. The join message includes an identifier of the first node and configuration information of the first node. The first switching device receives the join message, obtains the identifier of the first node based on the join message, determines, based on the identifier of the first node, a first zone corresponding to the first node, and sends a join notification message to a second node that belongs to the first zone. The join notification message includes the identifier of the first node and the configuration information of the first node.

Abstract: A node isolation method, a switching device, and an Ethernet storage system implement node isolation between zones in the Ethernet storage system. A first switching device in the Ethernet storage system determines a first access control list ACL rule between a first node and a second node, where the first switching device is an access device of the first node, the first node and the second node are located in the Ethernet storage system, and the first node and the second node correspond to a first zone; and if a packet whose source is the first node or a packet whose destination is the first node matches the first ACL rule, forwards the packet.
