A while ago I stumbled upon a great piece of code that could make your Cisco router a little less intimidating for your tier one tech support staff. The tier one team is useless the first ones that the customer engages when calling in a trouble.
Most of the time tier one is responsible for taking the customer information, creating a ticket and performing some basic trouble shooting steps, i.e. verify links and change passwords or provide application assistance, anything more in depth is forwarded to the tie 2 or 3 group.
With a simple menu configured on a Cisco router you can perform basic show commands that any tier 1 or 2 can use without the fear causing any intrusive down time to the production network, and the person performing the commands does not need to know the proper command syntax .
