Is it possible to configure AES on an SVM before creating the CIFS server

Last Updated:

Applies to

  • ONTAP 9
  • CIFS / SMB
  • Advanced Encyption Standard (AES)


Yes, you can modify the security options before creating the CIFS server on the vserver
Note: This will save time while creating multiple CIFS servers. If you create the CIFS server first, and then enable AES encryption, you will need to enter credentials again
cluster1::> cifs show -vserver <vserver_name>

cluster1::> cifs security modify  -vserver <vserver_name> -is-aes-encryption-enabled true
cluster1::> cifs security show -vserver <vserver_name>

Vserver: <vserver_name>
