Chapter 6 - NioNode SNMP control
68 Version 1.7.2.0 March 27, 2015
.
Introduction
NioNodes support Simple Network Management Protocol (SNMP). This allows a third party
system to monitor NioNodes in an NWare project and get and set control values.
Note: Currently, a third party system cannot use SNMP to interact with nControl and nTouch
180 projects. However, a project hosted by one of these nodes can monitor other devices on the
network using SNMP. For more information, see SNMP Components in the NWare Device
Reference.
SNMP OIDs and MIB files
SNMP uses a system of object identifiers (OIDs) or SNMP addresses to provide unique
locations for items of data. In each case, you can read a value or replace it with a new one.
NWare also includes a MIB (Management Information Base) file. The NioNode SNMP MIB
file is a standardized plain-text format file that defines the available OIDs. This is an
uncompiled MIB file.
The NioNode MIB file allows you to replace or add understandable names to guide you
through the otherwise all-numeric OIDs. The MIB file was designed alongside the SNMP
agent that runs on the NioNode hardware.
Enabling SNMP on the NioNode
The SNMP network service must be enabled on the NioNode before you can use SNMP. This
can be done using the front panel or the web interface.
 To enable SNMP using the front panel
1. From the main menu, select CONFIG to display the first configuration page, LAN
CONFIG, then select NEXT repeatedly until the NETWORK SERVICES page is
displayed.
2. Use the wheel and wheel push button to enable the SNMP service.
3. Select APPLY and press the wheel button to complete the adjustment.
 To enable SNMP using the web interface
1. Navigate to the Network screen.
