SMB Dialects
You can limit the number of dialects exported by Fusion File Share server using the global configuration setting, ‘dialects’:
dialects = SMB1 SMB2.002 SMB2.1 SMB3.0 SMB3.02 SMB3.1.1
If you do not want the SMB1 (CIFS) protocol exported, just exclude it from the list:
dialects = SMB2.002 SMB2.1 SMB3.0 SMB3.02 SMB3.1.1
