SNMP with Modular Messaging
Simple Network Management Protocol (SNMP) is a protocol used for the
management and monitoring of network elements. There are two kinds of
SNMP software - a manager, which makes configuration requests and
receives notifications, and an agent, which acts on behalf of the managed
or monitored element to respond to configuration requests and generate
notifications. An SNMP manager is often referred to as a Network
Management Station (NMS).
In the Modular Messaging context, the messaging application server
(MAS) and the Avaya Message Storage Server (MSS) are the managed
systems that interact with NMSs by means of SNMP.
SNMP can be used with Modular Messaging to perform the following
tasks:
! An NMS can perform queries to retrieve information from an
MSS. SNMP is read-only in the Modular Messaging system,
meaning that an NMS can query an MSS for information, but
cannot change that information.
! Modular Messaging (the MAS and MSS) can send alarm
information to specified NMSs, using notifications or traps. For
more information, see SNMP alarm notification
on page 5-15.
The Avaya MSS supports SNMP versions 1, 2c, and 3, whereas the MAS
supports SNMP versions 1 and 2c.
SNMP system queries
The Avaya MSS provides support to SNMP queries from Network
Management Stations (NMSs). When a suitably administered NMS
queries an MSS, by means of SNMP GET requests, the NMS retrieves
read-only information defined by Management Information Base - II
(MIB-II).
SNMP GET requests are restricted to specifically administered Network
Monitoring Stations.
Note: With this release of Modular Messaging, the MAS does not
provide support for SNMP GET requests Neither the MAS
nor the MSS provide support for SNMP SET requests.
