Scenario Operation Procedure
In the diagram above, the NMS server can manage multiple devices on the Intranet or a UDP-reachable network. "Router 1"
is one of the managed devices, and it has the IP address of 10.0.75.2 for the LAN interface and 118.18.81.33 for the WAN-1
interface. It serves as a NAT router.
The NMS manager prepares related information for all managed devices and records them in the NMS system. The NMS
system gets the status of all managed devices by using SNMP get commands.
