Snmp Agent Configuration - Microhard Systems Nano IP Series Operating Manual

6.0 Configuration

6.1.4.4 SNMP Agent Configuration

The Nano IP Series 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 re-
sources and measure performance.
SNMP may be used in several ways:
SNMP: Simple Network
Management Protocol
provides a method of

service to operate. This system must have full access to the IP Series network. Communica-
tions is in the form of queries (information requested by the management system) or traps
(information initiated at, and provided by, the SNMP agent in response to predefined events).
Objects specific to the Nano IP Series are hosted under private enterprise number 21703.
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 de-
vice (either responses to queries or device-sourced traps). The MIB in the device relates subrou-
tine 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 ob-
ject 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 sin-
gle 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.
