SNMP Diagnostic Agent: Simple Network Management Protocol

Overview

The Trio SNMP Agent interfaces the D Series diagnostic protocol to Network Management platforms such as SNMPC™ or HP Openview™. This allows multiple radio networks to be diagnosed via a wide area TCP/IP network.

The SNMP Agent is a software utility which simply resides on a PC workstation or server running under Windows NT.

Currently, the most widely used network management protocol is SNMP (Simple Network Management Protocol). It is transported by UDP (User Datagram Protocol) which is part of the IP (Internet Protocol) stack.

D Series diagnostics is supported by the diagnostic port on any D Series data radio or base station equipped with remote diagnostic facilities. Diagnostic data from all radios in a radio network can be obtained from any single radio in that network.

Trio’s TVIEW remote diagnostic software, running on a PC, allows a user to automatically and repetitively request diagnostic data from all radios in a radio network, also supporting trending, alarming and archiving of this data. However, when multiple data radio networks interface to a central SCADA platform via a Wide Area Network, the radio diagnostic data must be made available to the WAN’s Network Management platform, which monitors traditional network elements such as servers, switches and routers. These platforms support trending, alarming and archiving of data, and generally offer the operator a comprehensive graphical overview of the state of the entire network.

The SNMP Agent extracts the diagnostic data from a network of radios by repetitively polling them, and makes it available to the Network Management platform.
