2. Overview
The purpose of this MIB is to provide the means for
coordination between multiple management stations. That is,
the means by which the controlling and monitoring functions of
network management can be distributed amongst multiple
management stations. Such distribution facilitates the
scaling of network management solutions based on the SNMPv2 to
meet the needs of very large networks, or of networks composed
of multiple interconnected administrations. Specifically, this
MIB provides the means for one management station to request
management services from another management station.
2.1. A SNMPv2 Entity Acting in a Dual Role
A management station providing services to other management
station(s), is a SNMPv2 entity which acts in the dual role of
both manager and agent; the requests for service are received
through acting in an agent role (with respect to the managed
objects defined in this MIB), and the requested services are
performed through acting in a manager role.
2.2. Alarms, Events, and Notifications
In this initial version, this MIB defines the concepts of
"alarms", "events", and "notifications". Each alarm is a
specific condition detected through the periodic (at a
configured sampling interval) monitoring of the value of a
specific management information variable. An example of an
alarm condition is when the monitored variable falls outside a
configured range. Each alarm condition triggers an event, and
each event can cause (one or more) notifications to be
reported to other management stations using the Inform-Request
PDU.
Specifically, this MIB defines three MIB tables and a number
of scalar objects. The three tables are: the Alarm Table, the
Event Table, and the Notification Table.
