2.3. Access to Management Information
Three types of access to management information are provided by the
protocol. One type is a request-response interaction, in which a
SNMPv2 entity, acting in a manager role, sends a request to a SNMPv2
entity, acting in an agent role, and the latter SNMPv2 entity then
responds to the request. This type is used to retrieve or modify
management information associated with the managed device.
A second type is also a request-response interaction, in which a
SNMPv2 entity, acting in a manager role, sends a request to a SNMPv2
entity, also acting in a manager role, and the latter SNMPv2 entity
then responds to the request. This type is used to notify a SNMPv2
entity, acting in a manager role, of management information
associated with another SNMPv2 entity, also acting in a manager role.
The third type of access is an unconfirmed interaction, in which a
SNMPv2 entity, acting in an agent role, sends a unsolicited message,
termed a trap, to a SNMPv2 entity, acting in a manager role, and no
response is returned. This type is used to notify a SNMPv2 entity,
acting in a manager role, of an exceptional situation, which has
resulted in changes to management information associated with the
managed device.
