Disclosed are a RSCN method and system, a related device and a computer storage medium. The RSCN method applied to an Ethernet Node (ENode) device includes that: an RSCN message is received; and when it is determined that destination Media Access Control (MAC) contained in the RSCN message is ENode MAC, the RSCN message is distributed to a corresponding Virtual Node Port (VN_Port). The RSCN method applied to a Fiber Channel Over Ethernet (FCoE) Forwarder (FCF) includes that: network detection is performed; and when it is detected that a state to which attention is paid in a network changes, a first RSCN message is sent to an ENode device which pays attention to such a state change and succeeds in centralized notification capability negotiation with the FCF, destination MAC contained in the first RSCN message being ENode MAC. Disclosed are an ENode device, an FCF and an RSCN system.
