Hi experts. I'm struggling with the abysmal user interface experience introduced in ACI v5.1 for upgrading switch firmware. Having managed to blunder through an upgrade about a year ago using the new UI, I am now at the stage where I have my two upgr...

Hi @chkp-eviatars , @Wassim Aouadi is exactly right - it is completely a cosmetic change (and a welcome one - even more welcome would be remove the whole L2Out thing altogether - I've spoken about this here and here) You can verify that the change is...

Hi @Va.8427 , I don't believe you need to assign a Fabric ID as 2. Use Fabric ID=1 everywhere. My take on this is that when they created the initial setup, someone thought it would be a good idea to have a Fabric ID, then discovered that it is not re...
