Best Practice | On-Site Debugging
Introduction
This How To Note describes techniques for on-site debugging. It is in no way intended to be 
a comprehensive guide to debugging Allied Telesis equipment. Instead, it is aimed at passing 
on some techniques that have been found to be useful. Particularly, this document describes 
techniques which:
make it less likely that you will miss important pieces of information
make it simpler for someone else to analyse the debug information that you capture 
enable you to be more accurate in after-the-event discussions of what you saw.
