So we've been utilizing the Underlay/Fabrics wizard through Aruba Central to deploy our EVPN/VXLAN campus network. We already have 50 devices deployed with this method - 8325, 8360s, 6400s, 6300M stacks - and its worked pretty flawlessly up until this point. I've added 2 more 6300M VSF stacks into our Campus group and now it just errors out when trying to deploy the Underlay wizard.
It gets through all of the different tabs - Core, Aggregation, Access - I check the boxes to make the 6300 stacks "Access", and then I am met with a blank summary page that won't allow me to go any further. If I click "Finish" I am met with an "unknown error" pop up. If I click "cancel" I get a blank dialogue box that makes the entire screen unresponsive. I have to refresh the page to get out of it, which erases any changes I made in the wizard.
I've tried different browsers, incognito mode, clearing cache and cookies, removing the new stacks from the group and re-adding them, rebooting the stacks. I tried accessing central and running the wizard from a different internet connection. I opened a TAC case with Aruba but they haven't gotten back to me. Anyone got any other ideas I can try?
