devices are located at where UDP packets can reach from NMS.
The managed devices report urgent trap events to the NMS servers.
Use SNMPv3 version of protocol can protected the transmitting of SNMP commands and responses.

Scenario Operation Procedure
In the above diagram, the NMS server can manage multiple devices in the Intranet or a UDP-
reachable network. "Gateway 1" is one of the managed devices, and it has the IP address of
10.0.75.2 for LAN interface and 118.18.81.33 for WAN-1 interface. It serves as a NAT router.
At first stage, the NMS manager prepares related information for all managed devices and records
them in the NMS system. Then NMS system gets the status of all managed devices by using SNMP
get commands.
When the manager wants to configure the managed devices, the NMS system allows for that with
SNMP set commands. The "UserName1" account is used if the manager uses SNMPv3 protocol for
