==== Initial switch and router configuration ====

To configure a Cisco switch for the 1st time and set a hostname, you need to do the following:

  * Connect PC to switch using **parallel/console connection**
  * Open terminal emulation program (i.e. Putty)
    * Use serial connection (check Windows device manager - Ports(COM & LPT) to check which port to use)
    * Speed: 9600
    * Press connect
  * If the switch has not been configured (or has had a factory reset) you're asked to enter the initial configuration dialog; type **no**!:{{:marc:switch_1st_boot.png?direct&600|}}
  * Type the following commands:
<code>    Switch>en                                    enable gets you into privilege mode (Switch# prompt)
    Switch#?                                     shows available commands
    Switch#conf t                                configure terminal enters global configuration mode
    Switch#hostname switch1                      sets the hostname
    Switch#end                                   back to privilege mode
    Switch#copy running-config startup-config    writes the config to switch
    Switch#disable                               back to usermode</code>

  * Initial mode is __user mode__ (**Switch>** prompt)
  * Typing **enable** gets you into __privilege mode__ (**Switch#** prompt)
  * Typing **?** shows available commands
  * Tab completion is available but if it's clear that only 1 command is available, finishing it is not necessary.
  * **conf t** (configure terminal) enters __global configuration mode__ (input from terminal)
