I use this script to generate a template for switch like devices.
It isn't elegant, but it does the job!
After you run it make sure output has .xml extension then just import the
file.
This template says for a "Template_Brocade_5300", so if you want to change
it to something else then just search and replace all the
"Template_Brocade_5300" strings with whatever you want to call it.

Good luck
