What is Cisco EAP FAST? what is cisco eap-fast module and do i need it.
The term “vty” stands for Virtual teletype. VTY is a virtual port and used to get Telnet or SSH access to the device. The abstract “0 – 4” means that the device can allow 5 simultaneous virtual connections which may be Telnet or SSH. …
console 0 is the physical console port on the switch/router you plug into. line vty is when you remote into the switch/router via telnet or ssh. the config-line is letting you know you are currently in configuration mode for that specific line.
The Cisco IOS command-line interface (CLI) is the primary user interface used for configuring, monitoring, and maintaining Cisco devices. This user interface allows you to directly and simply execute Cisco IOS commands, whether using a router console or terminal, or using remote access methods.
The virtual terminal or “VTY” lines are virtual lines that allow connecting to the device using telnet or Secure Shell (SSH). Cisco devices can have up to 16 VTY lines. … These lines can be used to connect terminals or models to the device.
What does the command line vty 0 1 mean? The “0 1” represents the number of vty lines to which the following configu- ration parameters will be applied. The two virtual terminal connections are identified as 0, 1.
You can use the clear line command to clear any line on the system (vty or console). Using this command terminates any service, such as an FTP session, on this line and closes any open files. You can specify the absolute number to clear any line.
Examples of this include the Microsoft Windows, DOS Shell, and Mouse Systems PowerPanel. Command-line interfaces are often implemented in terminal devices that are also capable of screen-oriented text-based user interfaces that use cursor addressing to place symbols on a display screen.
Console Port Overview The console port is used to access the router and is located on the front panel of the Route Processor. For information on accessing the router using the console port, see Using Cisco IOS XE Software.
|This type of interface needs much less memory (RAM) in order to use compared to other types of user interfaces||Commands have to be typed precisely. If there is a spelling error the command will fail|
The use of “line console 0” command is to connect a switch/router through medium console. If there is only one console port, you can only choose “line console 0”. However if you have more than the number goes as 1,2,3,4 … You can set different or same password to all your console ports.
The command line is a text interface for your computer. It’s a program that takes in commands, which it passes on to the computer’s operating system to run. From the command line, you can navigate through files and folders on your computer, just as you would with Windows Explorer on Windows or Finder on Mac OS.
The Line Configuration Mode is used to manage the terminal line characteristics for output formatting. Command Modes. Exec > Global Configuration > Line Configuration.
As shown in the example, you can configure a simple password. The example also show the exec-timeout 0 0 command. This means that on the console port will never timeout. The default for this command is exec-timeout 10 0 which means that the console line will logoff when inactivity at this line reaches 10 minutes.
03-05-2006 03:17 PM. VTY lines are usually used for creating out-of-band management sessions to devices. If a password is not supplied on a vty line, that line cannot be used for managing the device. In some cases administrators may decide to let junior staff to use lines 0 – 4 and senior staff to use lines 5 – 15.
The Cisco IOS® command-line interface (CLI) offers context-sensitive help, a useful tool if you are a new user because at any time during an EXEC session, you can type a question mark (?) to get help. Two types of context-sensitive help are available: word help and command syntax help.
Login Local means you need a username and a password to get to the console session.
The no ip domain lookup tells the router to stop interacting with any DNS servers entirely. Having a DNS server configured is then a useless thing because it is not going to be used, anyway.
By default, an IOS device will disconnect a console or VTY user after 10 minutes of inactivity. You can specify a different inactivity timer using the exec-timeout MINUTES SECONDS line mode command.
Setting the session timeout parameter in a cisco router or switch is an easy task that will make your day to day work easy. router(config-line)#session-timeout 10 —- 10 is the amount of minutes we want to configure before timeout.
The main difference between GUI and CLI is that the Graphical User Interface (GUI) allows the user to interact with the system using graphical elements such as windows, icons, menus while the Command Line Interface (CLI) allows the user to interact with the system using commands.
CLI is that the word form used for Command Line Interface. … GUI stands for Graphical User Interface. GUI permits users to use the graphics to interact with an operating system. In graphical user interface, menus are provided such as : windows, scrollbars, buttons, wizards, painting pictures, alternative icons etc.
Common Language Infrastructure (CLI) CLI is a specification developed by Microsoft that describes the executable code and runtime environment. In simple terms this allows us to use various high-level programming languages on various machines without rewriting the code. CLI is divided into four main components.
Every Cisco router or a switch has a console port (also known as the management port) on its back side. Console port is used to connect a computer directly to a router or switch and manage the router or switch since there is no display device for a router or switch .
Types of RJ-45 Cabling Cisco products use the following types of RJ-45 cables: Straight-through. Crossover. Rolled.
Step 1 Locate the console port on the back of the Router/Switch. Step 2 Connect the console (or rollover) cable to the console port on the Router/Switch. Step 3 Use the correct adapter to connect the other end of the cable to your terminal or PC.
CLI Offers System Control Programmers, experienced computer users, or administrators may utilise a CLI. There are specific situations when typing text into the interface will provide faster results than simply using a GUI. Plus, CLIs can offer greater control over an operating system via succinct commands.
Disadvantages Command Line Interface (CLI): Commands have to be typed precisely. If there is a spelling mistake then the command will not respond or fail. If user can mis-type an instruction, it is often necessary to start from scratch again.
GUIs offer better multitasking and control Being more user-friendly than a command line (especially for new or novice users), a visual file system is utilized by more people. GUI users have windows that enable a user to view, control, manipulate, and toggle through multiple programs and folders at same time.
What does the command routerA(config)#line cons 0 allow you to perform next? Set the Telnet password.
TTY lines are physical connections. VTY lines are virtual connections.
A command line, also known as a command prompt, is a type of interface. A terminal is a wrapper program that runs a shell and allows us to enter commands. The console is a type of terminal.
- Go to the Start menu or screen, and enter “Command Prompt” in the search field.
- Go to Start menu → Windows System → Command Prompt.
- Go to Start menu → All Programs → Accessories → Command Prompt.
What is the Windows Command Prompt? Windows Command Prompt (also known as the command line, cmd.exe or simply cmd) is a command shell based on the MS-DOS operating system from the 1980s that enables a user to interact directly with the operating system.
The no shutdown command enables an interface (brings it up). This command must be used in interface configuration mode. It is useful for new interfaces and for troubleshooting. When you’re having trouble with an interface, you may want to try a shut and no shut.
Disable Unused Ports Navigate to each unused port and issue the Cisco IOS shutdown command. If a port later on needs to be reactivated, it can be enabled with the no shutdown command.
The power switch is on the right-hand side of each device, with a green LED indicating that the power is on. Click on this switch to turn it off.
- Router (A) — main mode;
- Adapter (B) — connect Ethernet devices to a Wi-Fi network;
- Repeater/Extender (C) — Wi-Fi extension;
- Access point/Extender (D) — expansion of the Wi-Fi area with Ethernet connection.
To exit interface configuration mode and to return to global configuration mode, enter the exit command. To exit interface configuration mode and to return to privileged EXEC mode, enter the end command, or press Ctrl-Z.
