The Management application obtains MRP status by monitoring the MRP traps that devices send. These traps are reported in the Master Log. Make sure MRP traps are enabled on the devices that are members of an MRP ring. For the MRP Status to display correctly, you must discover a proper ring through the Management application. If the link (edge) or a device (Vertex) is missing, the status does not display correctly; however, the feature may work.

MRP ring status is defined by specific rules and represented by one of the following icons:

TABLE 36

Icon	Description
	MRP ring is in normal operation.
Normal
	Both ports on a MRP-enabled device are disabled.
	No Master node on the MRP ring.
Error	Two or more Master nodes exist on the MRP ring.
	The Master node is in Forwarding or Forwarding state and none of the devices on the MRP ring
	are in an Error state.
