SMB 3.0 protocol is supported in DDI 5.5 and later version. It is a dialect “3.0” of SMB 2.0, DDI supports to detect SMB 2.0 traffic using dialect 3.0.
- DDI does not support new features only since dialect 3.0 (e.g. RDMA transport, encryption) but SMB Multi-Channel which is introduced in 3.0 is supported in DDI 5.7 and later version.
- DDI supports to detect SMB 2.0 traffic using dialect 3.0, so, the detection log (DDI web console > Detections > All Detections) shows SMB2 as a protocol for the corresponding detection even if SMB 3.0 is used.
