Just doing some lab testing on the C9300, I migrated one over to Meraki mode but I don't have any ability to configure IPv6 SVIs like I would if I had a MS390 in the dashboard. The release notes for MS15.21.1 say the migrated switches should have the same functionality as a MS390 which should have IPv6 SVI functionality on the dashboard yet I only see the ability to configure IPv4 interfaces, the dashboard doesn't show any IPv6 button like the config guides show either.
Did I miss something obvious?
