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 do the following operations:
• Query the operation status and input/output signals of the devices connected to the Controller.
• 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 support SNMP also support 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 SNMP v2.
All NMS that supports SNMPv2c can be used to access the
Controller. This includes HP OpenView, IBM NetView, Novell
ManageWise, SunNet Manager, and so on.
NMS Supported by SNMP v3
The ACU+ has SSL and SNMP v3 function, which makes the ACU+ 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.
Here we use https.

MIB Installation
Installation
The Controller’s MIB is named "Netsure_ESNA.mib". Contact your
Emerson representative for the location on the Web to download the MIB file.
Use the MIB loading function of the NMS to load the MIB database.
Refer to the User Manual provided with the NMS for the detailed loading method.
Contents of the Controller’s MIB
The contents of the MIB supported by the Controller’s SNMP agent
and the OID are listed in Table 6 . For the details, refer to the MIB
file named "Netsure_ESNA.mib".

Traps Alarm Traps Info
--
The SNMP agent can send the active alarms to the specified NMS and the User can define the lowest severity of the NMS accepted alarms.
--
In Table 6 , R means OID is read-only (GET), and R/W means OID can be read and modified (GET/SET).
Accessing the Controller through an NMS
Apply Administrative Authority
In order to use the NMS to manage the devices connected to the Controller, the administrative authority needs to be applied for the
NMS, that is, add the NMS information to the access list of SNMP agent.
Add NMS through Web Browser
Management System) Configuration Sub-Menu (version 3)” on page 126 for the method of adding NMS.
