The vserver export-policy rule show command displays information about export rules. The command output depends on the parameter or parameters specified with the command. If you do not specify any parameters, the command displays the following information:

Vserver name
Export policy name
Export rule index number
Access protocol
Client match
Read-only access rule
Read-write access rule

To display detailed information about a specific export rule, run the command with the -vserver , -policyname , and -ruleindex parameters. The detailed view provides all of the information in the previous list and the following additional information:

Anonymous ID
Superuser security type
Whether set user ID (suid) and set group ID (sgid) access is enabled
Whether creation of devices is enabled
NTFS security settings
Change ownership mode

You can specify additional parameters to display only the information that matches those parameters. For example, to display information only about export rules that have a read-write rule value of never, run the command with the -rwrule never parameter.

Parameters

[-rorule <authentication method>,…] - RO Access Rule

If you specify this parameter, the command displays information only about the export rule or rules that have the specified read-only rule. Possible values include the following:

sys - For an incoming request from a client matching the clientmatch criteria, allow read access to the volume if the security type of that incoming request is AUTH_SYS. The effective security type of the incoming request (to be used subsequently in evaluation of rwrule/superuser) becomes sys.
krb5 - For an incoming request from a client matching the clientmatch criteria, allow read access to the volume if the security type of that incoming request is Kerberos v5. The effective security type of the incoming request (to be used subsequently in evaluation of rwrule/superuser) becomes krb5.
krb5i - For an incoming request from a client matching the clientmatch criteria, allow read access to the volume if the security type of that incoming request is Kerberos v5 with integrity service. The effective security type of the incoming request (to be used subsequently in evaluation of rwrule/superuser) becomes krb5i.
krb5p - For an incoming request from a client matching the clientmatch criteria, allow read access to the volume if the security type of that incoming request is Kerberos v5 with privacy service. The effective security type of the incoming request (to be used subsequently in evaluation of rwrule/superuser) becomes krb5p.
ntlm - For an incoming request from a client matching the clientmatch criteria, allow read access to the volume if the security type of that incoming request is CIFS NTLM. The effective security type of the incoming request (to be used subsequently in evaluation of rwrule/superuser) becomes ntlm.
any - For an incoming request from a client matching the clientmatch criteria, allow read access to the volume regardless of the security type of that incoming request. The effective security type of the incoming request (to be used subsequently in evaluation of rwrule/superuser) remains the same as the security type of the incoming request.

If the security type of the incoming request is AUTH_NONE, read access will be granted to that incoming request as an anonymous user.

none - For an incoming request from a client matching the clientmatch criteria, allow read access to the volume as an anonymous user if the security type of that incoming request is not explicitly listed in the list of values in the rorule. The effective security type of the incoming request (to be used subsequently in evaluation of rwrule/superuser) becomes none.
never - For an incoming request from a client matching the clientmatch criteria, do not allow any access to the volume regardless of the security type of that incoming request.

You can specify a comma-separated list of multiple security types for an export rule. If you specify the security type as any or never , you cannot specify any other security types.

For an incoming request from a client matching the clientmatch criteria, if the security type doesn’t match any of the values listed in rorule (as explained above), access will be denied to that incoming request.

[-rwrule <authentication method>,…] - RW Access Rule

If you specify this parameter, the command displays information only about the export rule or rules that have the specified read-write rule. Possible values include the following:

sys - For an incoming request from a client matching the clientmatch criteria, allow write access to the volume if the effective security type (determined from rorule) of that incoming request is AUTH_SYS.
krb5 - For an incoming request from a client matching the clientmatch criteria, allow write access to the volume if the effective security type (determined from rorule) of that incoming request is Kerberos 5.
krb5i - For an incoming request from a client matching the clientmatch criteria, allow write access to the volume if the security type of that incoming request is Kerberos v5 with integrity service. The effective security type of the incoming request (to be used subsequently in evaluation of rwrule/superuser) becomes krb5i.
krb5p - For an incoming request from a client matching the clientmatch criteria, allow write access to the volume if the security type of that incoming request is Kerberos v5 with privacy service. The effective security type of the incoming request (to be used subsequently in evaluation of rwrule/superuser) becomes krb5p.
ntlm - For an incoming request from a client matching the clientmatch criteria, allow write access to the volume if the effective security type (determined from rorule) of that incoming request is CIFS NTLM.
any - For an incoming request from a client matching the clientmatch criteria, allow write access to the volume regardless of the effective security type (determined from rorule) of that incoming request.

If the effective security type (determined from rorule) of the incoming request is none, write access will be granted to that incoming request as an anonymous user.

none - For an incoming request from a client matching the clientmatch criteria, allow write access to the volume as an anonymous user if the effective security type (determined from rorule) of that incoming request is none.
never - For an incoming request from a client matching the clientmatch criteria, do not allow write access to the volume regardless of the effective security type (determined from rorule) of that incoming request.

You can specify a comma-separated list of multiple security types for an export rule. If you specify the security type as any or never , you cannot specify any other security types.

For an incoming request from a client matching the clientmatch criteria, if the effective security type (determined by rorule) doesn’t match any of the values listed in rwrule (as explained above), write access will be denied to that incoming request.

krb5i - For an incoming request from a client matching the clientmatch criteria, allow read access to the volume if the security type of that incoming request is Kerberos v5 with integrity service. The effective security type of the incoming request (to be used subsequently in evaluation of rwrule/superuser) becomes krb5i.
krb5p - For an incoming request from a client matching the clientmatch criteria, allow read access to the volume if the security type of that incoming request is Kerberos v5 with privacy service. The effective security type of the incoming request (to be used subsequently in evaluation of rwrule/superuser) becomes krb5p.
ntlm - For an incoming request from a client matching the clientmatch criteria and with the user ID 0, allow superuser access to the volume if the effective security type (determined from rorule) of that incoming request is CIFS NTLM.
any - For an incoming request from a client matching the clientmatch criteria and with the user ID 0, allow superuser access to the volume regardless of the effective security type (determined by rorule) of that incoming request.

If the effective security type (determined from rorule) of the incoming request is none, access will be granted to that incoming request as an anonymous user.

none - For an incoming request from a client matching the clientmatch criteria and with the user ID 0, allow access to the volume as an anonymous user if the effective security type (determined from rorule) of that incoming request is none.
never - For an incoming request from a client matching the clientmatch criteria and with the user ID 0, allow access to the volume as an anonymous user regardless of the effective security type (determined from rorule) of that incoming request.

Only export rules that were created in an earlier release can have the superuser parameter set to the security type never

You can specify a comma-separated list of multiple security types for superuser access. If you specify the security type as any , you cannot specify any other security types.

For an incoming request from a client matching the clientmatch criteria and with the user ID 0, if the effective security type doesn’t match any of the values listed in superuser (as explained above), the user ID is mapped to anonymous user.

[-allow-suid {true|false}] - Honor SetUID Bits in SETATTR

If you specify this parameter, the command displays information only about the export rule or rules that have the specified setting for set user ID (suid) and set group ID (sgid) access.

[-allow-dev {true|false}] - Allow Creation of Devices

If you specify this parameter, the command displays information only about the export rule or rules that have the specified setting for the creation of devices.

[-ntfs-unix-security-ops {ignore|fail}] - NTFS Unix Security Options

If you have specified this parameter for a particular export policy rule, then the command displays information about the UNIX security options that apply to that export policy rule. The setting can either prohibit (with value fail ) or allow (with value ignore ) UNIX-type permissions changes on NTFS (Windows) volumes when the request originates from an NFS client. If the Vserver NTFS UNIX security option is set to fail or allow for the Vserver, then this parameter is overridden.

[-ntfs-unix-security-ops-vs {fail|ignore|use-export-policy}] - Vserver NTFS Unix Security Options

If you specify this parameter, the command displays information about the UNIX security options that apply to all volumes in this Vserver. The setting can prohibit (with value fail ) or allow (with value ignore ) UNIX-type permissions changes on NTFS (Windows) volumes when the request originates from an NFS client, or you can set it to use-export-policy . If you set this parameter to fail or allow , this parameter overrides the individual UNIX security options set for the export policy rules. If you set this parameter to use-export-policy , the UNIX security options associated with the respective export policy rule is used.

[-chown-mode {restricted|unrestricted}] - Change Ownership Mode

If you have specified this parameter for a particular export policy rule, then the command displays information about the change ownership mode that applies to that export-policy rule. The setting can either allow only the root (with value restricted ) or all users (with value unrestricted ) to change file ownership provided the on-disk permissions allow the operation. If the Vserver change ownership mode is set to restricted or unrestricted for the Vserver, then this parameter is overridden.

[-chown-mode-vs {restricted|unrestricted|use-export-policy}] - Vserver Change Ownership Mode

If you specify this parameter, the command displays information about the change ownership mode that applies to all volumes in this Vserver. The setting can allow only the root (with value restricted ) or all users (with value unrestricted ) to change ownership of the files that they own, or you can set it to use-export-policy . If you set this parameter to restricted or unrestricted , this parameter overrides the individual change ownership mode set for the export policy rules. If you set this parameter to use-export-policy , the change ownership mode associated with the respective export policy rule is used.
