Applies to

  • ONTAP 9
  • SMB/CIFS
  • SMB3 Encryption

Answer

  • Before enabling SMB3 encryption at CIFS server level :
  • SMB encryption must be supported and enabled on the SMB client 
  • Windows clients beginning with Windows Server 2012 and Windows 8 support SMB encryption
  • After enabling SMB3 encryption at CIFS server level :
  • Encryption will not be in effect unless terminating the CIFS session and reconnecting
  • The existing sessions remains unencrypted
  • Any new session will be encrypted
  • SMB clients that do not support encryption, cannot connect to the SMB server where encryption is enabled
  • Any SMB2 client would not be able to access to the share that requires encryption on this vserver
