This separates the management access interface into the following modes:

  • User Exec
  • Privilege Exec
  • Global configuration mode

When you establish a console connection to a Cisco IOS device, you are taken directly into the User Exec mode by default. User Exec mode provides very limited capabilities for a user as it allows for basic troubleshooting and monitoring commands such as ping and traceroute.
