CISCO-IF-THRESHOLD-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.

Configuration and monitoring of the thresholds is done through threshold templates that can be assigned to any subset of interfaces on the network element. More than one threshold template can be assigned to a given interface. This MIB module should be used when it is desired to apply a common set of thresholds to a subset of the available interfaces. If a threshold is to be applied to only one interface, then the EVENT-MIB or the RMON-MIB may be used as simpler alternatives. If a threshold is to be applied to all available interfaces, then the EVENT-MIB may be used as a simpler alternative." REVISION "200109140000Z" DESCRIPTION "Second version of this MIB module." REVISION "200106140000Z" DESCRIPTION "Initial version of this MIB module." ::= { ciscoMgmt 218 } -- Textual Conventions CifthTemplateIndex ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "An arbitrary integer that uniquely identifies a threshold template. The value for each threshold template must remain constant at least from one re-initialization of the agent's network management system to the next re-initialization. The value may change when the agent's network management system is rebooted or re-initialized." SYNTAX Unsigned32 (1..1000) CifthTemplateIndexOrZero ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "A value of either '0' or a valid template index. The distinguished value '0' indicates no template or no unassigned template index values are available." SYNTAX Unsigned32 (0..1000) CifthThresholdIndex ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "An arbitrary integer that uniquely identifies a threshold within a threshold template. The value for each threshold must remain constant when the agent's network management system is rebooted or re-initialized." SYNTAX Unsigned32 (0..63) CifthThresholdList ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "A list of thresholds defined in a given template, in which each bit represents one threshold. The bits in the first octet represent thresholds identified by cifthThresholdIndex values 0 through 7, inclusive. The bits in the second octet represent thresholds identified by integer values 8 through 15, inclusive, and so forth. The least significant bit of an octet represents the threshold identified by the lowest integer value, and the most significant bit represents the threshold identified by the highest integer value. The figure shown below illustrates the format of a threshold list.

A bit value of '0' indicates that the threshold is not being exceeded in current operation (i.e., the threshold is cleared). A threshold list of length N, where N < 8, represents a threshold list for which thresholds N*8 through 63 have the value of '0'. A special case is a threshold list having a length of '0', which represents a threshold list of all zeros." SYNTAX OCTET STRING (SIZE(0..8)) CifthThresholdSeverity ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The severity of the condition when the threshold is fired. A smaller enumerated integer value indicates that the threshold exceeded condition is more severe. The value 'fail' indicates a hard failure condition where no data can be received, or where the data received has a large number of errors which makes it impossible to recover most of the data. The value 'degrade' indicates a soft failure condition in which data received on this interface is affected, but a significant portion of the data can be recovered. The value 'info' is used to raise attention to a condition that could possibly be an impending problem or to notify the customer of an event that improves operation."

For example, a value of cifthThresholdFiredValue of 5 on a gigabit ethernet interface indicates a threshold of 10^-5 times the interface speed, which is equal to 10,000 per second. When the value of this object is 'rateOfIncreaseExponentXIfSpeed', the polling interval between successive samples is determined automatically by the agent.

One reason for a template not to be operational on an interface to which it is assigned is when the interface has two (or more) templates assigned to it that contain thresholds on the same object with the same severity and direction, i.e., thresholds with the same values of cifthThresholdObject, cifthThresholdSeverity, and cifthThresholdDirection.
