Accessing the Controller via a Network
Management System (NMS)
General
The controller has an SNMP agent function.
Users can use a Network Management System (NMS) to perform
the following operations:
ï‚· Query the operation status and input/output signals of the
devices connected to the controller.
ï‚· Browse the active alarms.
When the controller generates alarms, the SNMP agent can be
configured to notify the NMS through TRAPS automatically.
NMS Supported by SNMP Agent
SNMP is a technology used for network management. The
technology is based on implementing an information base called
MIB (Managed Information Base). This MIB contains parameters
that are of interest from a management perspective. All LAN
connected equipment that supports SNMP also supports a default
MIB called MIB-II.
The SNMP Agent responds to requests received via the SNMP
protocol and also actively sends TRAPS to a specified manager
when certain MIB values change state. This is used to actively
inform a manager when an alarm situation is recognized.
NMS SUPPORTED BY SNMP V2
The SNMP agent of the controller supports SNMPv2.
All the NMS that supports SNMPv2c can be used to access the
controller. The NMS includes HP OpenView, IBM NetView, Novell
ManageWise, SunNet Manager, and so on.
NMS SUPPORTED BY SNMP V3
The NCU has SSL and SNMP V3 function, which makes the NCU
more powerful and more secure.
With SSL, you can browse/set the Webpage with https. Data is
encrypted in the transmission. You can also browse/set the MIB
library with SNMP v3. Data is also encrypted in the transmission.
