Cisco IOS uses a command line interface (CLI) for inputting commands when configuring Cisco Routers
Cisco business grade routers and switches use what is called IOS its a command based os meaning you have to enter commands to configure. There are console ports you can connect to a computer to a router where you can have direct access with the router via putty or hyper terminal (there might be more programs). once you set up like this you have access to the ios command line interface.
Showi ip route
router>enable router#configure terminal router(config)#line vty 0 4 router(config-line)#password cisco router(config-line)#login to configure router with telnet you must set up password or secret for privilieged mode.
To abort setup mode on a Cisco router, the user can press Ctrl + C. This key combination interrupts the setup process and returns the user to the command-line interface (CLI). Alternatively, users can also type exit to exit setup mode.
Configuring a physical router requires software like PUTTY. while configuring router on Software like packet tracer is done on CLI (i.e. command line interface).
To display all connected OSPFv2 routers, use the command show ip ospf neighbor in the router's command-line interface. This command provides a list of OSPF neighbors, including their state, router ID, and interface information. It helps in verifying OSPF adjacencies and troubleshooting OSPF connectivity issues.
Caller Line Identification, also known as caller ID.
Differentiate between Command line interface and Menus interface and example of each interaction style
A CLI router, or Command Line Interface router, is a network device that enables the routing of data packets between different networks and devices using command-line commands for configuration and management. Users interact with the router's operating system through a text-based interface, allowing for precise control over routing protocols, security settings, and network configurations. CLI routers are commonly used in enterprise environments for their flexibility and efficiency in network management.
It depends on your needs but for basic router settings, kindly see below example. You can copy this into your Cisco router command line interface. enable configure terminal no ip domain-lookup hostname R1 line con 0 login password secret logging synchronous exec-timeout 0 30 exit line vty 0 4 login password secret logging synchronous exec-timeout 0 30 exit do wr
The command is: clock rate 56000 So it will appear on the command line interface as: Router(config-if)# clock rate 56000 Reference: Networking by Jeffrey Beasley Chapter 6 page 216.
