It's really easy to replicate rules. It's the one that I've used; it was CLI-based. You can implement a large set of rules with CLI. You can just copy a script and add additional changes to the source and destination on the part. And so it's easy to do large zone-based rules.

I faced issues with the deployment and upgrade. In the QFX5110 series, features like ISSU and DSSQ should be improved. Upgrades should be smoother.

I don't think there's any improvement needed on Juniper QFX Series Switches, but I would like to see other cheaper plans for the license on the QFX series.
