(Optional) Enabling Clients to Automatically Clear Storage Space
Context
If storage space on a client is insufficient, the client cannot download system software. If this function is enabled, the client automatically deletes non-startup files if the storage space is insufficient.
Startup system software, including the running system software and the system software specified for next startup, will not be deleted when a client clears storage space.
This function is invalid for some types of file servers. If the file server is a TFTP server, this function does not take effect because the TFTP server does not return file size to clients. If an FTP or SFTP server does not support the function of returning file size, this function does not take effect. When an S switch serves as an FTP or a TFTP file server, the switch does not support the function of returning file size.
