I'm a newbie and self-study JNCIx-ENT. May I know if we have any effective simulation tool for Juniper switch products? I tried GNS3 but it apparently only good with routing.
I would suggest using vLab to simulate Virtual Switch (such as vQFX). There isn't much of difference to EX when compared. Follow the steps guided as follows - its all for free.
Thanks a lot, I'm going to try it
