1.4.3 SNMP Manager and Proxy Agents
In this use scenario, shown in Figure 7, an analyst with SNMP manager software
and internet access, manages one or more EMS systems with SNMP proxy agent
software and internet access. Using the SNMP manager, the analyst can request
and receive individual parameter values such as voltage readouts. The analyst can
also set certain parameters values such as operating mode to remotely configure
host/remote pairs. The interface also provides automatic reporting of alarms.
SNMP (Simple Network Management Protocol) is a common standard for inter-
network management of online devices using internet protocol (TCP/IP or UDP/
IP). SNMP manager and proxy agent software are available from ADC. The ADC
manager software is called “StarGazer.”
