The SNMP management system requests informa-
tion from a managed computer (called an SNMP
agent) such as the amount of hard disk space
available or the number of active sessions. The
SNMP management system can also initiate a
change to the configuration of an SNMP agent.
However, this is rare because most clients have
read-only access.

An SNMP agent.
The SNMP agent responds to SNMP management
system requests for information. Any computer
running SNMP agent software is an SNMP agent.
The Windows 2000 SNMP service, which is agent
software, responds to information requests from
one or more management systems. The SNMP ser-
vice can be configured to determine which statis-
tics are tracked and which management systems
are authorized to request information.
In general, SNMP agents do not originate mes-
sages, but only respond to them. A trap message
is the only agent-initiated SNMP communication.
A trap is an alarm-triggering event on an agent,
such as a system reboot or illegal access, which
provides enhanced security.
Management hosts and agents belong to an SNMP
community, which is a collection of hosts grouped
together for administrative purposes. Defining
communities provides security by allowing only
management systems and agents within the same
community to communicate.
