Industry Cellular Gateway
the Intranet and manage all devices that support SNMP protocol in the Intranet. Another one is the
Remote NMS to manage some devices whose WAN interfaces are connected together by using a
switch or a router with UDP forwarding. If you want to manage some devices and they all have
supported SNMP protocol, use either one application scenario, especially the management of devices
in the Intranet. In managing devices in the Internet, the TR-069 is the better solution. Please refer to
last sub-section.
Scenario Description
The NMS server can monitor and configure the managed devices by using SNMP protocol, and those
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.
The remote NMS with privilege IP address can manage the devices, but other remote NMS can't.
Parameter Setup Example
Following tables list the parameter configuration as an example for the Gateway 1 in above diagram
with "SNMP" enabling at LAN and WAN interfaces.
Use default value for those parameters that are not mentioned in the tables.

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.
