NVIRONMENT
EliteView uses Simple Network Management Protocol (SNMP), the most popular network management protocol.
SNMP was developed by the Internet Engineering Task Force (IETF) using the Internet Protocol (IP). SNMP was
originally designed to run on top of the UDP/IP transport protocol. EliteView currently supports transport
protocols including IP and IPX.
SNMP Roles
There are two defined roles in SNMP: manager and managed. The manager (EliteView) sends request messages and
the managed (device) sends responses and alarm messages.
SNMP uses a simple command-response style to request information or action. By sending a command to perform
an action, the manager is able to control the managed device. After the action is performed, the managed device
sends a response to indicate that the requested action has been completed.
Each command-response dialog is independent. The managed device does not maintain a “session” with the
manager.
Managing Data
Data in monitored devices are defined using the Management Information Base (MIB) model. Database
management functions are built into agent software using standard data structures. SNMP is based on the
“Concise MIB Definitions,” which are defined in RFC 1212.
