NEs supporting the alarm acknowledgment mechanism on 320G and 1600G devices
Question: If alarms are generated, NEs of earlier versions report the alarms to the NMS only for three consecutive times regardless of whether the NMS receives the alarms or not. In the latest version, NEs establish an alarm acknowledgment mechanism with the NMS. Therefore, when alarms are generated, the NEs continuously report the alarms to the NMS until they receive acknowledgment information from the NMS. For 4.0 and 5.0 platforms, which NEs on 320G and 1600G devices support the alarm acknowledgement mechanism? Answer: On the 4.0 platform, NEs support the alarm acknowledgement mechanisms since On the 5.0 platform, NEs support the alarm acknowledgement mechanisms since

Whether WDM devices support SNMP interfaces
The U2000, an NMS system for managing WDM devices, provides a variety of northbound interfaces (NBIs) for access to different operations support systems (OSSs). In the network architecture, the OSS is above the U2000 and manages NEs through the U2000. The U2000 communicates with the OSS through NBIs, such as XML, CORBA, SNMP, and performance text, to achieve quick integration with the carrier OSS.

    Whether the OSPF protocol is supported by WDM devices and functions of the OSPF protocol
    The OSPF protocol is required in the IP over DCC solution used in the DCN communication between WDM devices. The OSPF protocol is a dynamic routing protocol based on link status. It divides an AS (Autonomous System) into several areas. Route nodes exchange routing information in an area. The route nodes at the edge of an area make summary and exchange information with the routers in other areas. Each area is identified by different IDs and the area IDs have the same format as the IP addresses. Currently, the OSPF protocol of a WDM device supports only intra-area routes but does not support inter-area routes. Therefore, the gateway NE and non-gateway NEs managed by the protocol must be in the same OSPF area. By default, the line port of a WDM device is enabled with the OSPF protocol but the Ethernet port is not enabled with the OSPF protocol. To form a network through the Ethernet port, you need to modify the OSPF setting of the NE. In addition to the dynamic routing protocol, the NE supports static routes, which are manually configured. Static routes have a higher priority than dynamic routes. When a route conflict occurs, the device selects static routes.
