2 CLI Usage

This chapter provides information about using the command-line interface (CLI).

2.1 CLI Structure

Nokia's Operating System (OS) CLI is a command-driven interface accessible
through the console, Telnet and secure shell (SSH). The CLI can be used for
configuration and management of routers.
The CLI command tree is a hierarchical inverted tree. At the highest level is the
ROOT level. Below this level are other tree levels with the major command groups;
for example, configuration commands and show commands are levels below
ROOT.
The CLI is organized so related commands with the same scope are at the same
level or in the same context. Sublevels or subcontexts have related commands with
a more refined scope.

2.2 Navigating in the CLI

This section provides additional navigational and CLI syntax information.

2.2.1 CLI Contexts

Use the CLI to access, configure, and manage Nokia 7210 SAS devices. CLI
commands are entered at the command line prompt. Access to specific CLI
commands is controlled by the permissions set by your system administrator.
Entering a CLI command makes navigation possible from one command context (or
level) to another.
When you initially enter a CLI session, you are in the ROOT context. Navigate to
another level by entering the name of successively lower contexts. For example,
enter either the configure or show commands at the ROOT context to navigate to
the config or show context, respectively. For example, at the command prompt,
enter config. The active context displays in the command prompt.
