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.
