- 1. Introduction
-
- A network management system contains: several (potentially
- many) nodes, each with a processing entity, termed an agent,
- which has access to management instrumentation; at least one
- management station; and, a management protocol, used to convey
- management information between the agents and management
- stations. Operations of the protocol are carried out under an
- administrative framework which defines both authentication and
- authorization policies.
-
- Network management stations execute management applications
- which monitor and control network elements. Network elements
- are devices such as hosts, routers, terminal servers, etc.,
- which are monitored and controlled through access to their
- management information.
-
- Management information is viewed as a collection of managed
- objects, residing in a virtual information store, termed the
- Management Information Base (MIB). Collections of related
- objects are defined in MIB modules. These modules are written
- using a subset of OSI's Abstract Syntax Notation One (ASN.1)
- [1], termed the Structure of Management Information (SMI) [2].
-
- The management protocol, version 2 of the Simple Network
- Management Protocol [3], provides for the exchange of messages
- which convey management information between the agents and the
- management stations, including between management stations.
- It is the purpose of this document to define managed objects
- which describe the behavior of a SNMPv2 entity acting in both
- a manager role and an agent role.
-
-
- 1.1. A Note on Terminology
-
- For the purpose of exposition, the original Internet-standard
- Network Management Framework, as described in RFCs 1155, 1157,
- and 1212, is termed the SNMP version 1 framework (SNMPv1).
- The current framework is termed the SNMP version 2 framework
- (SNMPv2).

-
- 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.

-
-
- 2.3. Access Control
-
- The Administrative Model for SNMPv2 document [4] includes an
- access control model, which must not be subverted by allowing
- access to management information variables via the Alarm
- table. That is, access to a monitored variable via the Alarm
- table must be controlled according to the identity of the
- management station accessing the particular entry in the Alarm
- table.
-
- An entry in the Alarm table provides the means to configure
- the sampling of the value of a MIB variable in the MIB view
- associated with the specified context (which can refer to
- object resources that are either local or remote). The
- sampling is done by (conceptually or actually) issuing a
- SNMPv2 request to retrieve the variable's value. This request
- is authenticated and/or protected from disclosure according to
- a source party and a destination party pair which has access
- to the indicated context.
-
- Thus, to provide the required access control, the initial MIB
- view assigned, by convention, to parties on SNMPv2 entities
- that implement the snmpAlarmTable, must include the component:
-
- viewSubtree = { snmpAlarm }
- viewStatus = { excluded }
- viewMask = { ''H }
-
- Then, the MIB view associated with the context,
- requestContext, accessible by a requesting management station,
- can be configured to include specific Alarm table entries --
- the ones associated with those contexts to which the
- requesting management station has access.
-
- In particular, to provide a requestContext with access to the
- sampling context sampleContext, the following family of view
- subtrees would be included for the requestContext on the
- SNMPv2 entity acting in a dual role:
-
- { snmpAlarmEntry WILDCARD sampleContext }
-
- Which would be configured in the party MIB [5] as:
-
- contextIdentity = { requestContext }
- contextViewIndex = { ViewIndex }

-
- snmpAlarm OBJECT IDENTIFIER ::= { snmpM2MObjects 1 }
-
- -- This Alarm mechanism periodically takes statistical samples
- -- from variables available via SNMPv2 and compares them to
- -- thresholds that have been configured. The alarm table
- -- stores configuration entries that each define a variable,
- -- polling period, and threshold parameters. If a sample is
- -- found to cross the threshold values, an event is generated.
- -- Only variables that resolve to an ASN.1 primitive type of
- -- INTEGER (Integer32, Counter32, Gauge32, TimeTicks,
- -- Counter64, or UInteger32) may be monitored in this way.
- --
- -- This function has a hysteresis mechanism to limit the
- -- generation of events. This mechanism generates one event
- -- as a threshold is crossed in the appropriate direction. No
- -- more events are generated for that threshold until the
- -- opposite threshold is crossed.
- --
- -- In the case of sampling a deltaValue, an entity may
- -- implement this mechanism with more precision if it takes a
- -- delta sample twice per period, each time comparing the sum
- -- of the latest two samples to the threshold. This allows
- -- the detection of threshold crossings that span the sampling
- -- boundary. Note that this does not require any special
- -- configuration of the threshold value. It is suggested that
- -- entities implement this more precise algorithm.

-
- If it is detected by an error response of
