eAPI scripts written for the ACE training lab. These scripts make some assumptions, such
as there being switches numbered 10.0.0.x where x is the student switch number. If you've
taken the Arista ACE or APE classes, you will recognize the lab layout. 

Note that it is unlikely that these scripts will be useful as-is due to the nature of
the fact that they were written for the training racks. They are offered as examples
of working code that that you may ruthlessly copy what you need to make your scripts work.

SiteVariables.py  	A file with variables that are imported in order to make 
			the scripts portable between labs of different sizes.

ShowSwitchInfo.py  	This switch iterates through all of the switches in the lab and
			gets the output of "show version", out of which it displays 
			the following: 

			$ ./ShowSwitchInfo.py 

			Switch      Device Type          Serial#     Memory  EOS
			-------------------------------------------------------------
			Student-01:  DCS-7150S-24-F       JPE13160943 3978148 4.15.5M
			Student-02:  DCS-7150S-24-F       JPE13160960 4017112 4.12.5
			Student-03:  DCS-7150S-24-F       JPE13020368 3978148 4.15.5M
			Student-04:  DCS-7150S-24-CL-F    JPE13451306 3978148 4.15.5M
			Student-05:  DCS-7150S-24-CL-F    JPE13463487 3978148 4.15.5M
			[-- snip --]
 
			Note that it does this serially, so it can be slow. 

ShowVer.py  		A similar script, but this one uses Python threading and 
			curses so that it is *much* faster and updates multiple
			switches at once. This tool also reports memory util%. It
			creates output like this: 

	 		Student-01  EOS:[ 4.15.5M ]   Mem Used: [ 80.9% ]
 			Student-02  EOS:[ 4.12.5 ]    Mem Used: [ 50.3% ]
 			Student-03  EOS:[ 4.15.5M ]   Mem Used: [ 81.5% ]
 			Student-04  EOS:[ 4.15.5M ]   Mem Used: [ 81.1% ]
 			Student-05  EOS:[ 4.15.5M ]   Mem Used: [ 79.5% ]
			[-- snip --]


BaselineEOS.py  	This script will do the following for every student switch
			in the lab: 
	
			1) Delete all versions of EOS on flash:
			2) Copy the specified EOSVer to flash:
			3) Set the boot-config to " + EOSVer
			4) Issues the 'write erase' command (deletes startup-config)"
			5) Reload the switch (causing ZTP to trigger if enabled)

			This script uses Python threading and curses so that the entire
			lab of 20+ switches may be baselined in about six minutes vs.
			about 1/2 hour when done serially.  

			Output looks like this while running: 

 			Student-01  Init Baseline: [  ..  ]
 			Student-02  Init Baseline: [  ..  ]
 			Student-03  Init Baseline: [ Done ]
 			Student-04  Init Baseline: [  ..  ]
 			Student-05  Init Baseline: [ Done ]
			[-- snip --]
			

eAPIShRun.py		A script using eAPI that will get the running config and 
			save it to a time stamped file. This and ScreenScrapeShRun.py
			do the same thing via different methods. 

			Output looks like this: 

			$ ./eAPIShRun.py  
			Saving output to Student-20_2016-05-10_15-31-11


ScreenScrapeShRun.py	A script using pexpect (NOT eAPI!) that will get the running
			config and save it to a timestamped file. This and eAPIShRun.py
                        do the same thing via different methods.

			Output looks like this: 

			$ ./ScreenScrapeShRun.py  
			Saving output to Student-20_2016-05-10_15-23-38
