Cisco routers Operating system: IOS (Internetwork Operating System) IOS is used in routers / switches Muliple authentication levels Interfaces are denoted by slot/modul/number – FastEthernet 3/0

IOS command line tools ? -> Available commands command ? -> available parameters TAB or ? when typing a command : command completion Previous commands can be recalled using the arrows disabling command: „no” – no ip address; no shutdown

IOS authentication levels level / modeenter to levelpromptleave level user login >logout privilegedenable#disable exit logout generalconfigure terminal(config)#exit end interfaceinterface type x/x(config-if)#exit Authentication levels are layered – you can only go one level up or down. Shortcut: ctrl+z --> go back to privilegized mode

IOS default settings hostname enable secret xxx show running-config show startup-config show ip route Changes made are lost at reboot – to make them permanent copy the running config to the startup config with the command – copy running-config startup-config
