There are three sections to this post.  The first is all the commands that are common between a switch and a router.  The second is for switches only and the third is for routers.

There are several ways to learn  ios commands.  I prefer to NOT memorize a list of commands but rather what commands are used to accomplish a task.  I use flash cards to memorize some things but you are not usually asked to explain what a command does but rather what command must be used to accomplish a task.

I prefer to have a flash card with a task on one side and the commands to complete the task on the other.   I have listed a series of tasks here.  These are listed without the command prompt.  But you should be able to figure out pretty quickly what mode you are in.

SET TIME

Routers do not come with their own internal clocks like servers. You need to set the clock and timezone manually or configure NTP.

en
clock set hh:mm:ss month day year
conf t
clock timezone MST -7
clock summer-time CDT recurring

Now confirm the date and time by using the show clock command.

Cisco routers and switches do not have internal battery based clocks.  If you reboot you will loose the current date and time.  So instead of configuring them manually you might want to use a public NTP server.  The commands for this is pretty easy.  Do not use both a clcok set and an NTP server.

These are in order of how you would come across them if they were all setup.
