Applies to all Omada hardware.  Seems to make sense to me to code

RED - inactive/offline

YELLOW - undergoing management/transition/update (ie service interruption expected)

GREEN - active and passing traffic normally.

So in the above, I would expect 'Configuring' to be yellow (as I would Adopting and Provisioning and Updating) unless traffic is being passed normally.  We can argue about whether Isolated is yellow or red :)   I would say red as it would transition shortly to a yellow state once the mesh re-converges and then green, but should stay red if it cannot rejoin.
