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 NMS and the
managed devices, use SNMPv3 version of protocol.
The remote NMS without privilege IP address can't manage the "Gateway 1", since "Gateway 1" allows
only the NMS with privilege IP address can manage it via its WAN interface.
