Dell 3548 manual Using the CLI, Telnet Connection, Command Mode Overview

Telnet Connection

Telnet is a terminal emulation TCP/IP protocol. RS-232 terminals can be virtually connected to the local device through a TCP/IP protocol network. Telnet is an alternative to a local login terminal where a remote login is required.

The device supports up to four simultaneous Telnet sessions to manage the device. All CLI commands can be used over a telnet session.

To start a Telnet session:

1Select Start→ Run. The Run window opens.

2In the Run window, type Telnet <IP address> in the Open field.

3Click OK.

The Telnet session begins.

Using the CLI

This section provides information for using the CLI.

Command Mode Overview

The CLI is divided into command modes. Each command mode has a specific command set. Entering a question mark at the terminal prompt displays a list of commands available for that particular command mode.

In each mode, a specific command is used to navigate from one command mode to another.

During the CLI session initialization, the CLI mode is the User EXEC mode. Only a limited subset of commands are available in the User EXEC mode. This level is reserved for tasks that do not change the terminal configuration and is used to access configuration sub-systems such as the CLI. To enter the next level, the Privileged EXEC mode, a password is required (if configured).

The Privileged EXEC mode provides access to the device global configuration. For specific global configurations within the device, enter the next level, Global Configuration mode. A password is not 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. A password is not required.
