11 SNMP Native Agent Software
DEFINITY ONE includes a SNMP (Simple Network Mamagement Protocol) Native Agent. The agent provides
a SNMP interface to the system’s alarm and error tables, select performance measurements, and select
configuration data. The agent also supports SNMP traps for DEFINITY alarms and restarts, INTUITY alarms,
and Windows NT events.
DEFINITY Network Management (DNM), Avaya’s SNMP-based DEFINITY fault and performance
management product, also supports DEFINITY ONE. DNM runs on NT and UNIX workstations, and collects
fault, performance, and configuration data from DEFINITYs via the DEFINITY Proxy Agent. DNM receives
DEFINITY ONE data by sending SNMP requests to DEFINITY ONE’s native SNMP agent.
Users can integrate DNM with a Network Management System (NMS), either HP OpenView or Tivoli NetView.
This allows users to manage their DEFINITYs and data networks from a central location. The NMS catches traps
that native agents send, colors the DEFINITY ONE icons according to the traps’severity, and records the traps in
the NMS trap log. A network manager can use the NMS to copy and move the icons created for different
DEFINITY ONE devices to specific OpenView or NetView maps of their choosing. The network manager can
then look at the DEFINITY ONE data that the native agent provides by using the NMS’s MIB browser.
The SNMP native agent will run for at least four weeks without restarting.
Agent Administration
All SNMP agent administration can be performed from the command line and WEB
server. An administrator will specify the community string that the agent will use for
authentification. However, the agent must be restarted for community string
administration changes to take effect. In addition, an administrator can specify the
MIB access permissions, and whether traps can be received for up to 50 different
network managers (IP addresses). Again, the agent must be restarted for network
manager administration changes to take effect.
DEFINITY Data
The DEFINITY ONE SNMP agent provides a MIB interface to all of the
configuration and fault data that the DEFINITY Proxy Agent provides for DEFINITY
ECS devices (except, of course, for data that does not apply to DEFINITY ONE). The
supported data is as follows:
Via the SNMP MIB
The agent provides DEFINITY version information for the active switch processing
element (including memory resident software version, update identifier, and update
state). It also supports retrieval of DEFINITY alarms, errors, and restarts.
