Platform control mode
When the Intel
®
Command Line Interface is in Platform Control mode, you can issue commands to the
remote system.
To start an Intel
®
Command Line Interface session with dpccli, the network proxy dpcproxy must be
running, either on the managing console or a central network proxy system. However, by default you
should not have to do anything for the network proxy to be running, because the installation program
installs the network proxy and sets it up for automatic start upon reboot.
Serial Over LAN (SOL) mode
When the Intel
®
Command Line Interface is in SOL Console Redirection mode, you can perform, over
a LAN connection, any activity you could at the remote system’s console, including viewing the
remote system’s console output (SOL allows data from the server serial port to be redirected over
the LAN).
The Serial over LAN Console Redirection mode of Intel
®
Command Line Interface lets servers
transparently redirect the serial character stream from the baseboard UART to and from the managing
client system over the LAN. Serial over LAN has the following benefits compared to a serial interface:
 Eliminates the need for a serial concentrator
 Reduces the amount of cabling
 Allows remote management of servers without video, mouse, or keyboard (headless servers)
For a command prompt console, you must start dpccli before you can access the Intel
®
Command Line
Interface commands. The dpccli executable file acts as an interface between the console and the
network proxy. Once the interface is started, you can then connect to a server and enter commands.
4.5.4.3 DPCCLI versus Telnet
There are two basic ways to issue Intel
®
Command Line Interface commands through the network
proxy to a remote server: by using the console interface, called dpccli; or by using telnet. Both methods
are described in detail in the DPCCLI User Guide.
DPCCLI
An Intel
®
Command Line Interface session over dpccli requires a server name (or address) and login
(user and password), which can be supplied as arguments to the dpccli command.
Telnet
When using telnet to connect to the remote server (to issue Intel
®
Command Line Interface commands
and to operate in SOL mode), you must connect the telnet session to the dpcproxy by specifying (in the
telnet command line) the port on which dpcproxy is listening.
Once the Intel
®
Command Line Interface session over dpccli is running and the connection to the
intended server is established, you can begin issuing Intel
®
Command Line Interface commands to that
server at the dpccli prompt. If connecting through telnet, the same dpccli prompt is displayed when in
Platform Control mode (default), and you can issue Intel
®
Command Line Interface commands at the
dpccli prompt over telnet.
4.5.4.4 Using telnet for both Platform Control and SOL Modes
Serial over LAN mode requires a telnet session from the managing console to the Network Proxy
