SNMP Diagnostic Agent: Simple Network Management Protocol

SNMP Protocol

SNMP Protocol SNMP, the most widely used nertwork management protocol, transports data between the network management platform and the SNMP agent. The data in the agent is arranged in a manner defined by its MIB (Management Information Block) which is a formal description intelligible to all network management platforms. A MIB has been developed for the D Series SNMP agent, and its graphical representation is shown on the following pages. It is organised in a tree-like structure.

Each node of the structure is referenced by its name (as shown) and a reference to all the nodes above it in the tree. This is formed by a sequence of names separate by dots. For example, the pollDelay value is referenced by:

- org.dod.internet.private.enterprises.trio.
- products.tcdDiagnostics.pollDelay

The Trio D Series Diagnostic MIB consists of the following two main sections:

1. A set of values that are common for all the radios that are being supported. These include the lowest level branches from pollDelay through to latestPolledID.
2. A set of values that pertain to each radio being supported. These include the lowest level branches from radioID through to diagTableStatus. These values form a row in a table. There is one row for each radio that is supported. Each row is referenced by the value of radioID. For example, the value of the rssi data for radio of serial number 9750 is referenced by:
   - org.dod.internet.private.enterprises.trio.
   - products.tcdDiagnostics.diagTable.rssi.9750

The agent software is supported by an engineering user interface, for the setup and monitoring of the agent. All values, including the table values, can be read and written. Radios can be added or deleted from the table.
