Display information about SMB server security settings

You can display information about SMB server security settings on your storage virtual machines (SVMs). You can use this information to verify that the security settings are correct.

About this task

A displayed security setting can be the default value for that object or a non-default value that is configured either by using the ONTAP CLI or by using Active Directory group policy objects (GPOs).

Do not use the vserver cifs security show command for SMB servers in workgroup mode, because some of the options are not valid.

  1. Perform one of the following actions:

    If you want display information about…​ Enter the command…​

    All security settings on a specified SVM

    vserver cifs security show -vserver vserver_name

    A specific security setting or settings on the SVM

    vserver cifs security show -vserver _vserver_name_ -fields [fieldname,...] You can enter -fields ? to determine what fields you can use.


The following example shows all security settings for SVM vs1:

cluster1::> vserver cifs security show -vserver vs1

Vserver: vs1
