Use SMB share properties overview

Contributors

You can customize the properties of SMB shares.

The available share properties are as follows:

Share properties Description

oplocks

This property specifies that the share uses opportunistic locks, also known as client-side caching.

browsable

This property allows Windows clients to browse the share.

showsnapshot

This property specifies that Snapshot copies can be viewed and traversed by clients.

changenotify

This property specifies that the share supports Change Notify requests. For shares on an SVM, this is a default initial property.

attributecache

This property enables the file attribute caching on the SMB share to provide faster access of attributes. The default is to disable attribute caching. This property should be enabled only if there are clients connecting to shares over SMB 1.0. This share property is not applicable if clients are connecting to shares over SMB 2.x or SMB 3.0.

continuously-available

This property permits SMB clients that support it to open files in a persistent manner. Files opened this way are protected from disruptive events, such as failover and giveback.

branchcache

This property specifies that the share allows clients to request BranchCache hashes on the files within this share. This option is useful only if you specify “per-share” as the operating mode in the CIFS BranchCache configuration.

access-based-enumeration

This property specifies that Access Based Enumeration (ABE) is enabled on this share. ABE-filtered shared folders are visible to a user based on that individual user’s access rights, preventing the display of folders or other shared resources that the user does not have rights to access.

namespace-caching

This property specifies that the SMB clients connecting to this share can cache the directory enumeration results returned by the CIFS servers, which can provide better performance. By default, SMB 1 clients do not cache directory enumeration results. Because SMB 2 and SMB 3 clients cache directory enumeration results by default, specifying this share property provides performance benefits only to SMB 1 client connections.

encrypt-data

This property specifies that SMB encryption must be used when accessing this share. SMB clients that do not support encryption when accessing SMB data will not be able to access this share.
