Snmp - Microhard Systems BulletPlus Operating Manual

4.0 Configuration
4.13.4 Admin > SNMP
The BulletPlus may be configured to operate as a Simple Network Management Protocol
(SNMP) agent. Network management is most important in larger networks, so as to be able to
manage resources and measure performance. SNMP may be used in several ways:
SNMP: Simple Network
Management Protocol
provides a method of
A SNMP management system (a PC running SNMP management software) is required for this
managing network
service to operate. This system must have full access to the BulletPlus. Communications is in
devices from a single PC
the form of queries (information requested by the management system) or traps (information

devices are referred to as
SNMP agents.
An object is a variable in the device and is defined by a Management Information Database
(MIB). Both the management system and the device have a copy of the MIB. The MIB in the
management system provides for identification and processing of the information sent by a
device (either responses to queries or device-sourced traps). The MIB in the device relates
subroutine addresses to objects in order to read data from, or write data to, variables in the
device.
An SNMPv1 agent accepts commands to retrieve an object, retrieve the next object, set and
object to a specified value, send a value in response to a received command, and send a value
in response to an event (trap).
SNMPv2c adds to the above the ability to retrieve a large number of objects in response to a
single request.
SNMPv3 adds strong security features including encryption; a shared password key is utilized.
Secure device monitoring over the Internet is possible. In addition to the commands noted as
supported above, there is a command to synchronize with a remote management station.
The pages that follow describe the different fields required to set up SNMP on the BulletPlus.
MIBS may be requested from Microhard Systems Inc.
The MIB file can be downloaded directly from the unit using the 'Get MIB File' button on the
Network > SNMP menu.
