Use SNMPv3 version of protocol can protected the transmitting of SNMP commands
and responses.
The remote NMS with privilege IP address can manage the devices, but other remote
NMS can't.

Scenario Operation Procedure
In above diagram, the NMS server can manage multiple devices in the Intranet or a
UDP‐reachable network. The "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
him to do that by using SNMP set commands. The "UserName1" account is used if the
manager uses SNMPv3 protocol for configuring the "Gateway 1". Only the
"UserName1" account can let the "Gateway 1" accept the configuration from the NMS
since the authority of the account is "Read/Write".
Once a managed device has an urgent event to send, the device will issue a trap to the
Trap Event Receivers. The NMS itself could be one among them.
If you want to secure the transmitted SNMP commands and responses between the
Index skipping is used to reserve slots for new function insertion, when required.
