DELL Networking. CLI (Command Line Interface)

CLI, DELL, EXEC Mode

For example, DELL PowerConnect 3524

You can control the device directly via the terminal port or via a Telnet connection. If access is via a Telnet connection, ensure that the device specific IP-address, which will be used by the workstation to access the device and connect the device to use the CLI commands.

Telnet is an emulation on a TCP / IP terminal. RS-232 terminals can be virtually connected to the local device through a TCP / IP network protocol. Telnet is an alternative to the local terminal where you want the remote control of the device. The Switch supports up to 4 Telnet sessions to manage. All CLI commands can be used over a telnet session.

Configuring the device can be performed through the command line interface (CLI), which provides various command modes. Each command mode has its own set of specific commands. Enter "?" Question mark to call up the console prompt displays a list of commands available for the current mode.

The following modes are commonly used:

  • User EXEC mode,
  • Privileged EXEC mode,
  • Global Configuration mode,
  • Interface Configuration modes

To go to the next level, the Privileged EXEC mode, a password is required (if the password has been set). The Privileged EXEC mode provides access to a global device settings. For specific global device settings, go to the next level, Global Configuration mode. No password is required. The Global Configuration mode manages the device configuration on a global level. The Interface Configuration mode configures the device at the physical interface level. Interface commands which require subcommands have another level called the Subinterface Configuration mode. The password is also required.

User EXEC Mode

After entering the device, the EXEC command mode is engaged. Hint user level contains the host name followed by a triangular bracket (>).

For example:

console >

User EXEC commands allow you to connect to remote devices, changing terminal settings on a temporary basis, perform basic tests, view system information. List of User EXEC commands is displayed by a question mark input.

  2. When you see the password prompt, enter the password. The tooltip Privileged EXEC mode displays the name of the host with the following sign #

For example:

console#

Как установить OpenCV на Qt под Windows

Добавлю от себя: на Windows 10 x64 с MinGW 7.3.0 в CMake надо установить флаг OPENCV_ENABLE_ALLOCATOR_STATS=OFF, тогда всё скомпилится нормально.

Перехват обращения к локальным файлам QWebEngineView
