Via the SNMP
The agent allows retrieval of DEFINITY status data, system time, trunk group
information, board data, DS1 board data, ATM board data, port data, station data, and
data modules. It provides retrieval of information regarding trunk outage data, lightly-
used trunks, long and short trunk holding times, and trunk group performance
measurements. In addition, it provides tables of the DEFINITY’s external devices, of
the trunks in a trunk group, tables allowing access to the contents of the DEFINITY’s
bulletin board, and tables of the DEFINITY’s signaling groups.
SNMP Traps
The DEFINITY ONE agent generates SNMP traps for DEFINITY alarms and
restarts. As per requests by DEFINITY Proxy Agent customers, it also generates traps
for resolved alarms. The same traps are generated for all alarms. SNMP traps are sent
for eack new DEFINITY alarm, when DEFINITY alarms are resolved, and for
DEFINITY restarts.
The agent will generate SNMP traps for INTUITY AUDIX alarms that are sent to the
Global Alarm Monitor (GAM), and send SNMP traps for NT events that are sent to
the GAM.
For INTUITY AUDIX alarm traps, the SNMP natice agent also implements the
portions of the CornerStone MIB that apply to alarms. For DEFINITY data,
DEFINITY ONE uses a new MIB, which is a modified subset of the DEFINITY
Proxy Agent MIB.
DEFINITY ONE Co-Resident Modules
The SNMP agent uses the DEFINITY ONE co-resident modules as follows:
GAM
The SNMP agent will not send alarms to the GAM for INADS alarm reporting, but
will receive alarm noifications from the GAM. The SNMP agent generates TCP/IP
alarm notifications (traps) based on alarm notifications received from the GAM.
WatchDog
The SNMP agent is registered with the DEFINITY ONE WatchDog process. This
allows it to start automatically when the operating system is booted. An administrator
will also be able to start and stop the native agent manually. The SNMP native agent
will not subscribe to the DEFINITY ONE WatchDog “heartbeat” (i.e. handshake)
service.
