Diagnostic Information

This page displays RSTP-related data:

Field	Description
Service Status	Running	The RSTP bridge on the corresponding CPU is properly configured and running.
	Disabled	The RSTP bridge on the corresponding CPU is disabled.
	Unknown	The status of the RSTP bridge on the corresponding CPU is not known.
Last Topology Change	These values represent the date and time that the last topology change was received for the corresponding Bridge ID.
Redundancy Status	green	The designated Ethernet port is learning or formatting information.
	yellow	The designated Ethernet port is discarding information.
	gray	RSTP is disabled for the designated Ethernet port.
Router Bridge Statistics	Bridge ID	This unique bridge identifier is the concatenation of the bridge RSTP priority and the MAC address.
Router Bridge Statistics	Bridge Priority	The RSTP priority of the port.

CPU

(central processing unit) The CPU, also known as the processor or controller, is the brain of an industrial manufacturing process. It automates a process as opposed to relay control systems. CPUs are computers suited to survive the harsh conditions of an industrial environment.
