Cluster Instance Panel

The cluster instance panel shows summary information about the ONOS instances in the cluster. There will be one box per instance, showing the instance ID, IP address, and number of switches for which the instance is master.

The panel can be hidden (and subsequently re-shown) by pressing the 'I' (for "instances") key.

Image Added

The color coding indicates controller mastership; each device in the topology will be colored corresponding to which instance has mastership over it. For example:
