Cisco routers start to route IP packets only after IP address and mask have been configured.

Most Cisco router interfaces are disabled by default (are in shutdown state) and should be enabled with the no shutdown.

To make a router ready to route IPv4 packets on an interface, the first thing we need to do is enable the interface and assign it an IPv4 address. For example, show interfaces fastethernet 0/0 can be entered as sh int fa0/0. The show interfaces command lists the interfaces with a large amount of information per interface.Ĭommands that refer to router interfaces can be significantly shortened. The show ip interface brief command displays a list with one line per interface, with some basic information, including the interface static IP address and interface status. Two commands are commonly used to display the interfaces and their statuses. On routers, the interface numbers might be a single number, two numbers separated by a slash or three numbers separated by slashes.

Routers refer to interfaces in many commands, first by the type of interface (Ethernet, Fast Ethernet, Serial and so on) and then with a unique number of the router. For example, a 10-Mbps Ethernet interface can be configured with the interface Ethernet number command, a 10/100 interface can be configured using the interface fastethernet number command, and a 10/100/1000 interface can be configured with the interface gigabitethernet number command. Many of those interfaces support multiple speeds. Most Cisco routers have at least one Ethernet interface of some type.

LAN switches support Ethernet LAN interfaces, while routers support a variety of other types of interfaces, including serial, cable TV and DSL interfaces. Router InterfacesĪnother difference between Cisco switches and routers is that routers support a much wider variety of interfaces. Cisco routers are Level 3 devices and can do IP routing but not Layer 2 switching, so they support the show ip route command but not the show mac address-table command. For example, Cisco Layer 2 switches support the show mac address-table command but not the show ip route command, because that command lists IP routes at Level 3. However, a couple of things do work differently with routers than switches, such as the configuration of IP addresses and the CLI, because switches and routers do different things. The startup config (in NVRAM), running config (in RAM), and external servers (like TFTP), along with using the copy command to copy the configuration files and Cisco IOS images.Using the debug command to create log messages about certain events, so that any user can monitor those messages using the terminal monitor command.Configuring Ethernet interfaces using the speed and duplex commands.Navigating through different configuration mode contexts using commands like line console 0 and interface.Configuring an interface to be administratively disabled ( shutdown) or enabled ( no shutdown).Configuring the SSH encryption keys and login credentials.Configuring the hostname and interface description.Configuring the console and Telnet and enabling secret passwords.

Setup mode, which guides the user through a set of questions to create a simple initial configuration.

CLI help, command editing, and command recall features.

Enter or exit configuration mode using the configure terminal, end and exit commands, and the Ctrl+Z key sequence.

Here some other actions that are the same across devices:

For example, show, vty and enable password all work the same on both routers and switches. But these commands are not unique to routers many Cisco routers and switches use the exact same commands. Routers support a relatively large number of IOS commands my quick check found around 5,000 Command Line Interface (CLI) commands. Routers play a key role in enterprise networks because they connect the organization’s devices to the internet.
