[c-nsp] Questions Regarding Cisco 3750 switches

[Tóth András]

Hi,

On the 4948 you will have Fa1/1 or Gi1/1 by default because it's based
on Catalyst 4500 and uses module 1, therefore it uses 1/x.

On the 3750, you will have 1/0/x by default where you can change the
switch number to modify the first number to like 3/0/x. Otherwise, you
cannot really change interface numbers.
