svm_cifs
The svm_cifs table reports activity of the Common Internet File System Protocol subsystem. This is the Microsoft file-sharing protocol that evolved from the Server Message Block(SMB) application layer network protocol to connect PCs to Network Attached Storage(NAS) devices. This table supports SVM specific activity for SMB, SMB2, and SMB3 revisions of the CIFS protocol. The alias name for svm_cifs:node is svm_cifs_node.
