Terminology

138
An SNMP client (manager)
An SNMP server (agent)
A Management Information Base (MIB)
SNMP defines a client-server model in which a client (manager) obtains information
from the server (agent) through two mechanisms:
A request/response protocol by which the client configures and monitors the server.
In this instance, the information is solicited.
Asynchronous notifications (called traps) by which the server, on its own initiative,
reports notable changes in the router's status to the client. In this instance, the
information is unsolicited.
Table 16 on page 138 provides definitions for the basic SNMP terms.
