6.2 Simple Network Management Protocol
6.2.1 SNMP Overview
The Simple Network Management Protocol (SNMP) is one of many
protocols in the Internet Protocol (IP) suite. SNMP is the protocol
recommended specifically for the exchange of management information
between hosts residing on IP networks. Network management allows you
to monitor and control network devices remotely using conventional
computer network technology.
The SNMP management functions of the ETU01-A are provided by an
internal SNMP agent, which utilizes out-of-band communication over
standard 10BASE-T Ethernet. The SNMP agent is compliant with the
SNMPv1 standard. SNMP communication uses the User Datagram
Protocol (UDP). UDP is a connectionless transport protocol, part of the IP
suite. The SNMP protocol is an asynchronous command/response polling
protocol and operates at the OSI Layer 7 (Layer 7 is the Application
Layer. Other IP protocols that operate at this layer are FTP, Telnet,
SMTP, etc.). All management traffic is initiated by the SNMP-based
network management station. Only the addressed managed entity (agent)
answers the polling of the management station (except for trap messages).
All functions and settings accessible via the LCD or serial terminal
connection of the ETU01-A are also readable and settable via the Simple
Network Management protocol.
