Summary of the Module 2

  • All end devices and network devices require an operating system (OS).
  • Cisco IOS software separates management access into the following two command modes: User EXEC Mode and Privileged EXEC Mode.
  • Global configuration mode is accessed before other specific configuration modes. From global config mode, the user can enter different subconfiguration modes.
  • Each IOS command has a specific format or syntax and can only be executed in the appropriate mode.
  • Basic device configurations- hostname, password, encrypt passwords and banner.
  • There are two system files that store the device configuration: startup-config and running-config.
  • IP addresses enable devices to locate one another and establish end-to-end communication on the internet. Each end device on a network must be configured with an IP address.
