Overview
This document is a supplement to the Dialogic® DSI Signaling Server user
manuals describing the operation and capabilities of the Distributed
Structured Management Information (DSMI) SNMP agent as it is used on the
Dialogic® DSI Signaling Server in SIU and SGW modes.
The existing, basic SNMP agent is already described by the User Manuals and
therefore no further reference is made to it in this manual.
DSMI SNMP operation provides comprehensive reporting of the state and
alarms for Dialogic® DSI Signaling Server components (e.g., board instances,
SS7 links, fans etc.) through SNMP. This information is classified into the
following object groups:
Management
System
Platform
IP
Boards
SS7
SIGTRAN
Access.
Each of these object groups comprise one or more objects. These objects,
together with the object groups, are defined in separate SNMP MIB definition
files. This implementation of the DSMI SNMP agent only supports „read‟
(SNMP GET) requests from SNMP managers. There is no support for „write‟
(SNMP PUT) requests.
DSMI SNMP support is implemented as a SNMP subagent and provides
support of SNMP versions 1 (RFC1157), 2c (RFC1901) and 3 (RFC2571).
The DSMI SNMP agent provides status information about various aspects of
the Server‟s behavior. It also implements SNMP TRAP/NOTIFY events alerting
SNMP manager software to various conditions that the agent has detected.
Up to 32 SNMP managers can be defined to receive TRAP notifications. These
managers can be configured to receive TRAP notifications supported by the
various versions of SNMP.
