I wasn't able to find if this is possible nor any plans if it's not currently. R750 allows me to deliver a trunk for multiple SSIDs configured, I can also configure a management VLAN which is used for communication between multiple R750s. However, the web interface for management seems to still only work with untagged packets. This forces me to deliver a hybrid port.
Is this by design, or is there any way to move the web ui to a separate VLAN?
The first tab sets the IP for the master AP, but this management tab is for the management IP which will float across the APs if the master goes down. You don’t want the management IP to be set via DHCP or you wouldn’t know what it is.
