ALARM-MIB device MIB details by RFC
ALARM-MIB file content
The SNMP protocol is used to for conveying information and commands between agents and managing entities. SNMP uses the User Datagram Protocol (UDP) as the transport protocol for passing data between managers and agents. The reasons for using UDP for SNMP are, firstly it has low overheads in comparison to TCP, which uses a 3-way hand shake for connection. Secondly, in congested networks, SNMP over TCP is a bad idea because TCP in order to maintain reliability will flood the network with retransmissions.
Management information (MIB) is represented as a collection of managed objects. These objects together form a virtual information base called MIB. An agent may implement many MIBs, but all agents must implement a particular MIB called MIB-II [16]. This standard defines variables for things such as interface statistics (interface speeds, MTU, octets sent, octets received, etc.) as well as various other things pertaining to the system itself (system location, system contact, etc.). The main goal of MIB-II is to provide general TCP/IP management information.

ResourceId ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "A unique identifier for this resource. The type of the resource can be determined by looking at the OID that describes the resource. Resources must be identified in a consistent manner. For example, if this resource is an interface, this object MUST point to an ifIndex and if this resource is a physical entity [RFC2737], then this MUST point to an entPhysicalDescr, given that entPhysicalIndex is not accessible. In general, the value is the name of the instance of the first accessible columnar object in the conceptual row of a table that is meaningful for this resource type, which SHOULD be defined in an IETF standard MIB."

If there is no applicable varbind, the value of this object MUST be zero. Note that the value of alarmModelVarbindIndex acknowledges the existence of the first two obligatory varbinds in the InformRequest-PDU and SNMPv2-Trap-PDU (sysUpTime.0 and snmpTrapOID.0). That is, a value of 2 refers to the snmpTrapOID.0. If the incoming notification is instead an SNMPv1 Trap-PDU, then an appropriate value for sysUpTime.0 or snmpTrapOID.0 shall be determined by using the rules in section 3.1 of [RFC3584]" DEFVAL { 0 } ::= { alarmModelEntry 4 } alarmModelVarbindValue OBJECT-TYPE SYNTAX Integer32 MAX-ACCESS read-create STATUS current DESCRIPTION "The value that the varbind indicated by alarmModelVarbindIndex takes to indicate that the alarm has entered this state.

If the name is equal to or a subtree of the value of this object, for purposes of computing the value of AlarmActiveResourceID the 'prefix' will be the matching portion, and the 'indexes' will be any remainder. The examination of varbinds ends with the first match.

Setting this object to notInService cannot be used as an alarm suppression mechanism. Entries that are notInService will disappear as described in RFC2579. This row can not be modified while it is being referenced by a value of alarmActiveModelPointer. In these cases, an error of `inconsistentValue' will be returned to the manager. This entry may be deleted while it is being referenced by a value of alarmActiveModelPointer. This results in the deletion of this entry and entries in the active alarms referencing this entry via an alarmActiveModelPointer. As all read-create objects in this table have a DEFVAL clause, there is no requirement that any object be explicitly set before this row can become active. Note that a row consisting only of default values is not very meaningful." ::= { alarmModelEntry 10 } -- Active Alarm Table -- alarmActiveLastChanged OBJECT-TYPE SYNTAX TimeTicks MAX-ACCESS read-only STATUS current DESCRIPTION "The value of sysUpTime at the time of the last creation or deletion of an entry in the alarmActiveTable.

This SHOULD be the same as, or contain as a prefix, the applicable snmpNotifyFilterProfileName if the SNMP-NOTIFICATION-MIB DEFINITIONS [RFC3413] is supported. An implementation may allow multiple named alarm lists, up to some implementation-specific limit (which may be none).

For SNMPv1 alarms this is the community string from the Trap. Note that care MUST be taken when selecting community strings to ensure that these can be represented as a well-formed SnmpAdminString. Community or Context names that are not well-formed SnmpAdminStrings will be mapped to zero length strings.
