   Table 1 Role parameters

   Parameter		Description
   IP address		This parameter is mandatory. Select an existing IP address from the drop-down list box.
   Port		If you keep this field blank, the default UDP port is used.
   Topology function		If you select ON, the Commander is enabled to collect topology information so that you can deploy and maintain the network based on the topology.
   Automatic client discovery		If you select ON, the Commander automatically learns client information, including each client's MAC address, ESN, IP address, device type, device model, system software name, configuration file name, and patch file name. This function enables the Commander to monitor and manage basic information and version files for clients on the network.
   Aging time of offline clients		If you select ON, set an aging time. If the Commander does not receive status information from a client in 2 minutes, the Commanders considers the client offline. When the number of clients managed by a Commander reaches the upper limit, new client information cannot be added to the Commander. To release the space occupied by offline clients in the client database, configure an aging time for offline clients. When the aging time expires, the Commander deletes the offline client.
   File Server Configuration	Server type	Options are FTP, SFTP, and TFTP. NOTE: FTP and TFTP cannot ensure secure file transfer. SFTP is recommended on networks that require high security.
   	IP address	Enter the IP address of the file server.
   	User name	Set the user name used to log in to the file server.
   	Password	Set the password used to log in to the file server.
   Download File Configuration	File activation mode	Options are Default mode and Reset mode. By default, if downloaded files include a software package (*.cc), clients activate all the downloaded files by resetting. In a batch upgrade, if downloaded files include a configuration file, clients activate all the downloaded files by resetting.
   	File activation time	Options are Immediate, Delayed, and Scheduled. If you select Delayed or Scheduled, specify a time.
   	Automatically clear storage space	If you select yes, clients will delete non-startup system software packages if they do not have sufficient space for downloaded files. NOTE: 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 cannot return the file size, this function does not take effect yet.
   Automatic Backup Configuration	File backup mode	Options are Non-backup, Save backup file as new file, and Overwrite original file.
   Default File Settings	System file name	If you do not specify any file information, the default file information is used. You can specify a maximum of three self-defined files.
   	System version
   	Configuration file name
   	Patch file name
   	Web file name
   	License file name
   	User-defined file name
