====== Cisco - Modes ======

There are three modes:

  * **User EXEC mode**:  Basic monitoring – Prompt looks like: Switch>
  * **Privileged EXEC mode**:  Access to other router commands – Prompt looks like: Switch#
  * **Global configuration mode**:  Commands that affect the entire system – Prompt looks like: Switch (config)#
