Description: Fore Systems interface creation MIB providing objects for dynamically creating and managing ATM virtual interfaces on ForeRunner switch ports.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is Fore-Ifcreate-MIB?

Fore-Ifcreate-MIB is a vendor-specific MIB from Fore Systems, covering the ForeRunner family of ATM and Frame Relay switches. It exposes configuration and control objects used to dynamically create logical interfaces, specifically an ifCreateTable for provisioning FR/ATM and FUNI services and an ifConversionTable that maps a service identifier to its assigned interface index. Rather than hardware sensor data, this MIB is used to monitor the software-side provisioning state of the switch, letting an operator verify whether a requested virtual interface or service has actually been instantiated and which ifIndex it was assigned, catching failed or inconsistent interface creation. It depends closely on the standard IF-MIB (RFC 2863) ifTable/ifIndex model, since every entry it creates must correspond to a valid interface index in that standard table. It is typically deployed on carrier or enterprise ATM/Frame Relay edge switches where circuits and services are provisioned dynamically rather than fixed at boot. Engineers can download the Fore-Ifcreate-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Fore-Ifcreate-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Monitoring Examples

An operator provisioning a new FR/ATM service on a ForeRunner switch would query the ifCreateTable to confirm the service was created and check the assigned interface index, then cross-reference the ifConversionTable to verify the service-ID-to-ifIndex mapping is correct. A missing row in ifCreateTable after a provisioning request signals a failed interface creation, while a stale or duplicate mapping in ifConversionTable can reveal ifIndex reuse problems after a service is torn down and re-provisioned.

OIDs

OID symbolic	OID numeric	Type	Access	Description
TES ifReserveNextIndex	1.3.6.1.4.1.326.1.17.1	TestAndIncr	read-write	The next available IfIndex for service creation.
ifCreateTable	1.3.6.1.4.1.326.1.17.2		not-accessible	The Interface creation table
ifCreateEntry	1.3.6.1.4.1.326.1.17.2.1		not-accessible	Entry associated with IfCreate table entry.
NUM ifCreateIfIndex	1.3.6.1.4.1.326.1.17.2.1.1	InterfaceIndex	read-only	The interface index of this service.
INT ifCreateIfType	1.3.6.1.4.1.326.1.17.2.1.2	INTEGER	read-create	The type of the interface to be created.
ROW ifCreateRowStatus	1.3.6.1.4.1.326.1.17.2.1.3	RowStatus	read-create	This object is used to create new rows in this table, and to delete existing rows.
INT ifCreateServiceStatus	1.3.6.1.4.1.326.1.17.2.1.4	INTEGER	read-create	This object specifies the status of the service under creation. The service status is set to underConfig at the beginning of the service creation process. The service creation process is not considered completed until all the related MIB objects are set up properly. Then the service status is set to active. The default status is inactive.
STR ifCreateName	1.3.6.1.4.1.326.1.17.2.1.5	DisplayString	read-create	The object specifies the name assigned to the interface.
INT ifCreateIfTrapSupport	1.3.6.1.4.1.326.1.17.2.1.6	INTEGER	read-create	The object specifies whether interface traps should be generated for this interface.
STR ifCreateServiceId	1.3.6.1.4.1.326.1.17.2.1.7	DisplayString	read-create	The object specifies the serviceID assigned to the interface.
ifConvertToIfIndexTable	1.3.6.1.4.1.326.1.17.3		not-accessible	The Interface conversion table for converting service id (i.e. board id, netmod id, port id, channel id) into service ifindex.
ifConvertToIfIndexEntry	1.3.6.1.4.1.326.1.17.3.1		not-accessible	An entry associated with ifConvertToIfIndex table.
I32 ifConvertToIfIndexBoardId	1.3.6.1.4.1.326.1.17.3.1.1	Integer32	read-only	This object identifies the board id associated with a FUNI or FRATM service id in BNPC notation.
I32 ifConvertToIfIndexNetmodId	1.3.6.1.4.1.326.1.17.3.1.2	Integer32	read-only	This object identifies the netmod id associated with a FUNI or FRATM service id in BNPC notation.
I32 ifConvertToIfIndexPortId	1.3.6.1.4.1.326.1.17.3.1.3	Integer32	read-only	This object identifies the port id associated with a FUNI or FRATM service id in BNPC notation.
I32 ifConvertToIfIndexChannelId	1.3.6.1.4.1.326.1.17.3.1.4	Integer32	read-only	This object identifies the channel id associated with a FUNI or FRATM service id in BNPC notation.
NUM ifConvertToIfIndexIfIndex	1.3.6.1.4.1.326.1.17.3.1.5	InterfaceIndex	read-only	The service ifindex that is associated with this service id.
