getVlanCounters.py

#!/usr/bin/env python

'''
This script relies on a few things
1. you cave a .eapi.conf file in your ~/
    ** example .eapi.conf
    [connection:tg254]
    host: 172.28.129.56
    username: admin
    #password: (this test env did not need a password)
    transport: https
2. You have enabled eapi on your switch: conf; management api https commands; no shut
3. You have enabled vlan counters on the 7280R
    tg254.08:41:49(config)#hardware counter feature vlan in
    tg254.08:47:33(config)#hardware counter feature vlan out
4. you have installed pyeapi 'pip install pyeapi'
There is a lot of formatting and likely stripping away some of the output for your needs. Let me know if you need help with that.
