Your boss would like a small light installed on his desk to indicate the health of the network. If it is green everything is fine, yellow means there is potential trouble, and red means there is trouble
If you could only use one feature of network performance to control the light , What would it be and why ?
If you could use a second feature, what would it be and how you combine it with the first to control the light ?
How could SNMP protocol be used to help you implement this system?
