   Table 4-18 NFS share client properties

   Parameter	Description	Value
   Permission	Permission for a client to access the NFS share. The permissions include: Read-only: Only reading the files in the share is allowed. Read-write: Any operation is allowed.	[Default value] Read-only
   Write Mode	Write mode of the NFS share client. The modes include: Synchronous: The data written to a share is written into disks immediately. Asynchronous: The data written to a share is written into the cache first, then into disks. NOTE: If a client mounts an NFS share in asynchronous mode, data may be lost in the event that the client and storage system are faulty at the same time.	[Default value] Synchronous
   Permission Constraint	Determines whether to retain the user identity (UID) and group ID (GID) of a shared directory. all_squash: The UID and GID of a shared directory are mapped to user nobody and are applicable to public directories. no_all_squash: The UID and GID of a shared directory are reserved.	[Default value] no_all_squash
   Root Permission Constraint	Controls the root permission of a client. root_squash: The client cannot access the storage system as user root. If a client accesses the storage system as user root, the client will be mapped as user nobody. no_root_squash: A client can access the storage system as user root and user root can fully manage and access the root directory.	[Default value] root_squash
   Source Port Verification	Determines whether to enable source port verification. secure: Clients can use ports 1 to 1023 to access NFS shares. insecure: Clients can use any port to access NFS shares.	[Default value] insecure
   Anonymous User ID	Sets the UID and GID of the user accessing the shared directory who is mapped as an anonymous user. NOTE: This parameter is available in V500R007C20 and later versions.	[Value range] 0 to 4294967294 [Default value] 65534
