Hi,

I'm about to install a couple of CRS326 switches. I was going to use version 6, but they shipped with 7 and are impossible to downgrade. Is there any particular version that's recommended? They won't be doing anything fancy, but are absolutely mission critical. Basically just a couple of VLANs, and they will be connected to each other via QSFP.

More stable 7 than what? What version is installed?

Than any other version. 7.8 is installed.
