Once in the configuration branch, a user can enter the configuration system-level commands that apply to the entire router at the global configuration level.
Cisco Packet Tracer Examples Able Order How To Operate TheAfter reading this post, a user will understand how to operate the IOS CLI to configure and manage an IOS Cisco router.Packet Tracer is a tool that allows you to simulate real networks.It provides three main menus that allow you to: Add devices and connect them via cables or wireless; Select, delete, inspect, label, and group components within your Network; Manage your network. Here are some Cisco terms to help you understand this theme as you read this post: Tab 1. Ciscos terms:) A Cisco IOS router command line interface can be accessed through a console or connection, modem connection, or a telnetssh session. Regardless of which connection method is used, access to the IOS command-line interface is generally referred to as an EXEC session. ![]() EXEC user level allows a person to access only a limited amount of basic monitoring commands. Privileged EXEC level allows a person to access all of the routers commands (eg, configuration and management) and can be password protected to allow only authorized users the ability to configure or maintain the router. Once an EXEC session is established, commands within Cisco IOS are hierarchically structured. In order to be able to configure the router, it is important to understand this hierarchy. Fig 1. To illustrate this hierarchy, this presents a simple high-level schematic diagram of some IOS commands; IOS CLI hierarchy Command options and applications vary depending on the position within that hierarchy (Img from Cisco IOS basic usage ) To illustrate this hierarchy, Fig. IOS commands: For example, when an EXEC session is started, the router will show a Router prompt. The EXEC user level does not contain all commands that can control (for example, reload or configure) the operation of the router. To list the commands available at the EXEC user level, type a question mark ( ) At the Router prompt. This feature is called context-sensitive help.) Critical commands (for example, configuration, and management) require the user to be at the privileged EXEC level. To switch to the privileged EXEC level, type enable at the Router prompt. If an activation password is configured, the router will then ask for the password. When the correct activation password is entered, the prompt router will change to Router, indicating that the user is now at the privileged EXEC level. To return to the EXEC user level, type disables at the Router prompt. Entering a question mark ( ) in the privileged EXEC level will now reveal many more command options than are available at the EXEC user level. The basic CLI modes that we will be referring to below are as follows: Router User EXEC Mode Router Privileged EXEC mode Router(config) Router(config-if) Router(config-line) Note: For security reasons, the router will not echo the password that is entered. ![]() The configuration command options will not be available until the user has navigated to the configuration branch of the IOS CLI structure.
