EMail: Orly_n@rad.co.il" DESCRIPTION "The MIB module to allow insertion of selected circuit into the ifTable." REVISION "200201030000Z" -- January 3, 2002 DESCRIPTION "Initial version, published as RFC 3201" ::= { mib-2 94 } -- Textual Conventions CiFlowDirection ::= TEXTUAL-CONVENTION STATUS current DESCRIPTION "The direction of data flow thru a circuit. transmit(1) - Only transmitted data receive(2) - Only received data both(3) - Both transmitted and received data." SYNTAX INTEGER { transmit(1), receive(2), both(3) } ciObjects OBJECT IDENTIFIER ::= { circuitIfMIB 1 } ciCapabilities OBJECT IDENTIFIER ::= { circuitIfMIB 2 } ciConformance OBJECT IDENTIFIER ::= { circuitIfMIB 3 } -- The Circuit Interface Circuit Table -- -- This table is used to define and display the circuits that -- are added to the ifTable. It maps circuits to their respective -- ifIndex values. ciCircuitTable OBJECT-TYPE SYNTAX SEQUENCE OF CiCircuitEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "The Circuit Interface Circuit Table." ::= { ciObjects 1 } ciCircuitEntry OBJECT-TYPE SYNTAX CiCircuitEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "An entry in the Circuit Interface Circuit Table." INDEX { ciCircuitObject, ciCircuitFlow } ::= { ciCircuitTable 1 } CiCircuitEntry ::= SEQUENCE { -- -- Index Control Variables -- ciCircuitObject RowPointer, ciCircuitFlow CiFlowDirection, ciCircuitStatus RowStatus, -- -- Data variables -- ciCircuitIfIndex InterfaceIndex, ciCircuitCreateTime TimeStamp, -- -- Data Persistence -- ciCircuitStorageType StorageType } ciCircuitObject OBJECT-TYPE SYNTAX RowPointer MAX-ACCESS not-accessible STATUS current DESCRIPTION "This value contains the RowPointer that uniquely describes the circuit that is to be added to this table. Any RowPointer that will force the size of OBJECT IDENTIFIER of the row to grow beyond the legal limit MUST be rejected. The purpose of this object is to point a network manager to the table in which the circuit was created as well as define the circuit on which the interface is defined. Valid tables for this object include the frCircuitTable from the Frame Relay DTE MIB(FRAME-RELAY-DTE-MIB), the frPVCEndptTable from the Frame Relay Service MIB (FRNETSERV-MIB), and the aal5VccTable from the ATM MIB (ATM MIB). However, including circuits from other MIB tables IS NOT prohibited." ::= { ciCircuitEntry 1 } ciCircuitFlow OBJECT-TYPE SYNTAX CiFlowDirection MAX-ACCESS not-accessible STATUS current DESCRIPTION "The direction of data flow through the circuit for which the virtual interface is defined. The following define the information that the virtual interface will report. transmit(1) - Only transmitted frames receive(2) - Only received frames both(3) - Both transmitted and received frames. It is recommended that the ifDescr of the circuit interfaces that are not both(3) SHOULD have text warning the operators that the particular interface represents only half the traffic on the circuit." ::= { ciCircuitEntry 2 } ciCircuitStatus OBJECT-TYPE SYNTAX RowStatus MAX-ACCESS read-create STATUS current DESCRIPTION "The status of the current row. This object is used to add, delete, and disable rows in this table. When the status changes to active(1), a row will also be added to the interface map table below and a row will be added to the ifTable. These rows SHOULD not be removed until the status is changed from active(1). The value of ifIndex for the row that is added to the ifTable is determined by the agent and MUST follow the rules of the ifTable. The value of ifType for that interface will be frDlciEndPt(193) for a frame relay circuit, atmVciEndPt(194) for an ATM circuit, or another ifType defining the circuit type for any other circuit. When this object is set to destroy(6), the associated row in the interface map table will be removed and the ifIndex will be removed from the ifTable. Removing the ifIndex MAY initiate a chain of events that causes changes to other tables as well. The rows added to this table MUST have a valid object identifier for ciCircuitObject. This means that the referenced object must exist and it must be in a table that supports circuits. The object referenced by ciCircuitObject MUST exist prior to transitioning a row to active(1). If at any point the object referenced by ciCircuitObject does not exist or the row containing it is not in the active(1) state, the status SHOULD either age out the row or report notReady(3). The effects transitioning from active(1) to notReady(3) are the same as those caused by setting the status to destroy(6). Each row in this table relies on information from other MIB modules. The rules persistence of data SHOULD follow the same rules as those of the underlying MIB module. For example, if the circuit defined by ciCircuitObject would normally be stored in non-volatile memory, then the row SHOULD also be non-volatile." ::= { ciCircuitEntry 3 } ciCircuitIfIndex OBJECT-TYPE SYNTAX InterfaceIndex MAX-ACCESS read-only STATUS current DESCRIPTION "The ifIndex that the agent assigns to this row." ::= { ciCircuitEntry 4 } ciCircuitCreateTime OBJECT-TYPE SYNTAX TimeStamp MAX-ACCESS read-only STATUS current DESCRIPTION "This object returns the value of sysUpTime at the time the value of ciCircuitStatus last transitioned to active(1). If ciCircuitStatus has never been active(1), this object SHOULD return 0." ::= { ciCircuitEntry 5 } ciCircuitStorageType OBJECT-TYPE SYNTAX StorageType MAX-ACCESS read-create STATUS current DESCRIPTION "The storage type used for this row." ::= { ciCircuitEntry 6 } -- The Circuit Interface Map Table -- -- This table maps the ifIndex values that are assigned to -- rows in the circuit table back to the objects that define -- the circuits. ciIfMapTable OBJECT-TYPE SYNTAX SEQUENCE OF CiIfMapEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "The Circuit Interface Map Table." ::= { ciObjects 2 } ciIfMapEntry OBJECT-TYPE SYNTAX CiIfMapEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "An entry in the Circuit Interface Map Table." INDEX { ifIndex } ::= { ciIfMapTable 1 } CiIfMapEntry ::= SEQUENCE { -- -- Mapped Object Variables -- ciIfMapObject RowPointer, ciIfMapFlow CiFlowDirection } ciIfMapObject OBJECT-TYPE SYNTAX RowPointer MAX-ACCESS read-only STATUS current DESCRIPTION "This value contains the value of RowPointer that corresponds to the current ifIndex." ::= { ciIfMapEntry 1 } ciIfMapFlow OBJECT-TYPE SYNTAX CiFlowDirection MAX-ACCESS read-only STATUS current DESCRIPTION "The value contains the value of ciCircuitFlow that corresponds to the current ifIndex." ::= { ciIfMapEntry 2 } -- Change tracking metrics ciIfLastChange OBJECT-TYPE SYNTAX TimeStamp MAX-ACCESS read-only STATUS current DESCRIPTION "The value of sysUpTime at the most recent change to ciCircuitStatus for any row in ciCircuitTable." ::= { ciObjects 3 } ciIfNumActive OBJECT-TYPE SYNTAX Gauge32 MAX-ACCESS read-only STATUS current DESCRIPTION "The number of active rows in ciCircuitTable." ::= { ciObjects 4 } -- Conformance Information ciMIBGroups OBJECT IDENTIFIER ::= { ciConformance 1 } ciMIBCompliances OBJECT IDENTIFIER ::= { ciConformance 2 } -- -- Compliance Statements -- ciCompliance MODULE-COMPLIANCE STATUS current DESCRIPTION "The compliance statement for SNMP entities which support of the Circuit Interfaces MIB module. This group defines the minimum level of support required for compliance." MODULE -- this module MANDATORY-GROUPS { ciCircuitGroup, ciIfMapGroup, ciStatsGroup } OBJECT ciCircuitStatus SYNTAX INTEGER { active(1) } -- subset of RowStatus MIN-ACCESS read-only DESCRIPTION "Row creation can be done outside of the scope of the SNMP protocol. If this object is implemented with max-access of read-only, then the only value that MUST be returned is active(1)." OBJECT ciCircuitStorageType MIN-ACCESS read-only DESCRIPTION "It is legal to support ciCircuitStorageType as read- only as long as the value reported in consistent with the actual storage mechanism employed within the agent." ::= { ciMIBCompliances 1 } -- -- Units of Conformance -- ciCircuitGroup OBJECT-GROUP OBJECTS { ciCircuitStatus, ciCircuitIfIndex, ciCircuitCreateTime, ciCircuitStorageType } STATUS current DESCRIPTION "A collection of required objects providing information from the circuit table." ::= { ciMIBGroups 1 } ciIfMapGroup OBJECT-GROUP OBJECTS { ciIfMapObject, ciIfMapFlow } STATUS current DESCRIPTION "A collection of required objects providing information from the interface map table." ::= { ciMIBGroups 2 } ciStatsGroup OBJECT-GROUP OBJECTS { ciIfLastChange, ciIfNumActive } STATUS current DESCRIPTION "A collection of statistical metrics used to help manage the ciCircuitTable." ::= { ciMIBGroups 3 } END
