Switch Port Activity

This is a script to pull switch port stats from our access switches in our network. The data pulled in this script is used for ‘right sizing’ and network planning. 

We can then export the results, and pivot table them to see the % of switch ports in use/not-in use. I’ll add this attachment later.

/**
* @intent Show int counters on Arista & IOS-XE Switches 
* @description 
* 1. Check to see what switch ports have had no traffic accross the wire for sizing and planning. 
* 2. Match on platform.os
* 3. Use the information from the custom command 'show int counters'.
* 4. Get counts of switch ports on that device so we can use to calculate % in use
