You can't "stack" 3550.  Stacking using StackWise is the exclusive domain of the 2960S, 3750 and 3850.

You can, however, use an old-school feature called Switch Clustering.  Why would you want to use Switch Clustering is beyond me as it does not have any benefits.

I'm training and my tutor asked me to Stacker 2 switch cisco 3550 he told me that this is possible and I can not find any documentation on the 3550 switch stack. I have a 3550 switch 12 port and port 11 and 12 have a GigaStack card.

Ok, that is indeed Switch Clustering.

My opinion:  Try to UNDERSTAND what switch clustering is.  Don't spend too much time on this as not alot of people are using this method since the introduction of StackWise.
