[c-nsp] 3750 stack

[Bøvre Jon Harald]

Hi

We have a number of 3750 stacks with anything from 2 to 8 switches.

Our standard when configuring new stack:
First switch numbered 9, second switch numbered 8
Switch # 9 given priority 15 (highest)

Advantage?
We are able to add new switches 7 -6- 5 -> without any downtime and does add switches during daytime with no impact to customers
