When you add a node to the Orion Platform or remanage a node, its status is Unknown until the data is polled. Unknown status tells you that the node, or the sub-element (interface or volume) cannot be polled for response time and status. This is more accurate, because the device tells you that the sub-element is Down. Status of sub-elements, such as interfaces and volumes, is detected using SNMP. See Get more details about the node in the NPM Getting Started Guide for more details. The device could be down, but there might also be a routing problem, an intermediary device could be down, or something could have blocked the packet on its way to or from the device. ICMP only tells you the NPM did not receive a response for the ping request. If the node still does not respond, you are notified you that the node is Down. NPM sends a ping request and if the response is not returned, it places the node into the Warning state and fast-polls the device for 120 seconds. This article provides information about the device status in NPM, how it is polled, and what you can do if your nodes or interfaces have the Unknown status.īy default, node status is detected using ICMP.

#Ethernet status down driver#
The driver implementation of the Ethernet PHY is a typical part of a Network Software Pack, since PHY is typically not integrated into the microcontroller. The driver implementation of the Ethernet MAC is a typical part of a Device Family Pack (DFP) that supports the peripherals of the microcontroller family.
The following header files define the Application Programming Interface (API) for the Ethernet interface: The Ethernet PHY connects typically to the Ethernet MAC using an MII (Media Independent Interface) or RMII (Reduced Media Independent Interface).īlock Diagram of a typical Ethernet Interface Wikipedia offers more information about the Ethernet.
