Navigating the CLI

Initial mode

When you initiate a session, you can log in with operator or administrator privileges. Whichever login you use, the CLI is always set to operator exec (non-privileged exec) mode by default upon startup. This mode allows you to examine the state of the system using a subset of the available CLI commands.

System changes

In order to make changes to the system, the administrator exec (privileged exec) mode must be entered. The enable user interface command is used for this purpose (the enable command is only accessible if you are logged in as an administrator). Once in administrator exec mode, all of the system commands are available to you.

Configuration

To make configuration changes, the configuration mode must be entered by using the configure command in the administrator exec mode.

Changing Modes

The exit command moves the user up one level in the mode hierarchy (the same command works in any of configuration modes). For example, when in pvc configuration mode, typing exit will take you to framerelay configuration mode.

The exit command terminates a CLI session when typed from the operator exec mode.

A session can also be terminated by using the logout command within any mode.

Command help

To see a list of all CLI commands available within a mode, type a question mark <?> or the <tab> key at the system prompt in the mode of interest. A list of all available commands is displayed. Commands that have become available in the current mode are displayed at the bottom of the list, separated by a line. Commands from higher hierarchy levels are listed at the top.

You can also type the question mark or the <tab> key while in the middle of entering a command. Doing so displays the list of allowed choices for the current keyword in the command. Liberal use of the question mark functionality is an easy and effective way to explore the command syntax.

The No form

Almost every command supports the keyword no. Typing the no keyword in front of a command disables the function or “deletes” a command from the configuration. For example, to enable the DHCP server trace tool, enter the command debug dhcp-server. To subsequently disable the DHCP server trace, enter the command no debug dhcop-server.

Command completion

You can use the <tab> key in any mode to carry out command completion. Partially typing a command name and pressing the <tab> key causes the command to be displayed in full up to the point where a further choice has to be made. For example, rather than typing configure, typing conf and pressing the <tab> key causes the
