1 Using the CLI This chapter describes how to start using the CLI and describes the command editing features to assist in using the CLI. CLI Command Modes Introduction To assist in configuring the device, the Command Line Interface (CLI) is divided into different command modes. Each command mode has its own set of specific commands. Entering a question mark "?" at the system prompt (console prompt) displays a list of commands available for that particular command mode.
PAGE 26
w w w. d e l l . c o m | s u p p o r t . d e l l . c o m When starting a session, the initial 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 configuration. To enter the next level, the Privileged EXEC mode, a password is required. The Privileged EXEC mode gives access to commands that are restricted on User EXEC mode and provides access to the device Configuration mode.
PAGE 27
The default host name is Console unless it was changed using the hostname command in the Global Configuration mode. Privileged EXEC Mode Privileged access is password protected to prevent unauthorized use because, many of the privileged commands set operating system parameters. The password is not displayed on the screen and is case sensitive. Privileged users enter directly into the Privileged EXEC mode.
PAGE 28
w w w. d e l l . c o m | s u p p o r t . d e l l . c o m To enter the Global Configuration mode, at the Privileged EXEC mode prompt enter the command configure and press . The Global Configuration mode prompt is displayed. The Global Configuration mode prompt consists of the device host name followed by (config) and #.
PAGE 29
• Port Channel — Contains commands to configure port-channels, for example, assigning ports to a port-channel. Most of these commands are the same as the commands in the Ethernet interface mode, and are used to manage the member ports as a single entity. The interface portchannel Global Configuration mode command is used to enter the Port Channel Interface Configuration mode. • SSH Public Key-chain — Contains commands to manually specify other device SSH public keys.
PAGE 30
w w w. d e l l . c o m | s u p p o r t . d e l l . c o m 2 Enter the following commands to begin the configuration procedure: Console> enable Console# configure Console(config)# 3 Configure the device and enter the necessary commands to complete the required tasks. 4 When finished, exit the session with the exit command. When a different user is required to log onto the system, use the login Privileged EXEC mode command. This effectively logs off the current user and logs on the new user.
PAGE 31
To assist in using the CLI, there is an assortment of editing features. The following features are described: • Terminal Command Buffer • Command Completion • Keyboard Shortcuts Copying and Pasting Text Up to 100 lines of text (i.e., commands) can be copied and pasted into the device. NOTE: This editing features are for Telnet only. NOTE: It is the user’s responsibility to ensure that the text copied into the device consists of legal commands only.
PAGE 32
w w w. d e l l . c o m | s u p p o r t . d e l l . c o m There is a standard default number of commands that are stored in the buffer. The standard number of 10 commands can be increased to 216. By configuring 0, the effect is the same as disabling the history buffer system. For information about the command syntax for configuring the command history buffer, see history size. To display the history buffer, see show history.
PAGE 33
CLI Command Conventions When entering commands there are certain command entry standards that apply to all commands. The following table describes the command conventions. Convention Description [] In a command line, square brackets indicate an optional entry. {} In a command line, curly brackets indicate a selection of compulsory parameters separated by the | character. One option must be selected.

2 Command Groups Introduction The Command Language Interface (CLI) is a network management application operated through an ASCII terminal without the use of a Graphical User Interface (GUI) driven software application. By directly entering commands, you achieve greater configuration flexibility. The CLI is a basic command-line interpreter similar to the UNIX C shell.
PAGE 36
w w w. d e l l . c o m | s u p p o r t . d e l l . c o m Command Groups The system commands can be broken down into functional groups as shown below. Command Group Description AAA Commands Configures connection security including authorization and passwords. ACL Commands Configures ACL on the device. Address Table Commands Configures bridging Address Tables. Clock Commands Configures clock commands on the device. Configuration and Image Files Commands Manages the device configuration files.
PAGE 37
SSH Commands Configures SSH authentication. Syslog Commands Manages and displays syslog messages. System Management Commands Configures the device clock, name and authorized users. TACACS Commands Configures TACACS+ commands. TIC Commands Configures and displays TIC information. Tunnel Commands Configures tunnel routing configurations. User Interface Commands Describes user commands used for entering CLI commands. VLAN Commands Configures VLANs and displays VLAN information.

Command Mode Interface Configuration (Ethernet, port-channel) mode. User Guidelines • An access port does not dynamically join a VLAN because it is always a member in only one VLAN. • Membership in an untagged VLAN is propagated in the same way as in a tagged VLAN. That is, the PVID is manually defined as the untagged VLAN VID.
