The following tables show how the EVS encryption, share encryption, and reject unencrypted access options affect SMB3 and SMB2 clients when they try to access files on a NAS Server.

Note: SMB3 Encryption does not affect SMB1 clients. To prevent unencrypted access by SMB1 clients, you must turn off the SMB1 server by using the
smb-min-supported-version 2 command.
