SMB Configuration

The SMB service provides access to filesystems using the SMB protocol. The supported SMB versions are: SMB 1, SMB 2.0, SMB 2.1, SMB 3.0, and SMB 3.1. To share filesystems over SMB, configure the filesystem as described in Filesystem Properties. The following tables show the supported and unsupported features for SMB 3.1, SMB 3.0, and SMB 2.1.

It is strongly advised to upgrade clients from SMB 1 to at least SMB 2.0 because SMB 1 has known security and performance issues that are resolved in later SMB versions.
