Description: Fore Systems FUNI (Frame-based UNI) MIB providing configuration and statistics for the Frame-based ATM UNI interface on ForeRunner switches.

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-Funi-MIB?

Fore-Funi-MIB is a vendor-specific SNMP module from Fore Systems (later Marconi) for the Frame-based ATM User-Network Interface (FUNI) supported on ForeRunner ATM switches. It exposes configuration and status data for FUNI connections, including administrative and operational state of each frame-based ATM link and profile settings governing early/partial packet discard (EPD/PPD) congestion behavior. Network operators use it to monitor hardware/software status of FUNI interfaces, most importantly whether a configured connection is administratively enabled and operationally up, a frontline indicator of link or interface fault. Like most Fore Systems enterprise MIBs it is typically layered alongside standard IF-MIB and the vendor's core ATM MIBs rather than used standalone. It would be deployed in legacy ATM WAN/backbone environments where ForeRunner switches provide frame-relay-to-ATM interworking at a customer or carrier edge. Engineers can download the Fore-Funi-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Fore-Funi-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 administrator would poll funiConnAdminStatus against funiConnOperStatus for each FUNI connection to detect a mismatch indicating the link is enabled but not passing traffic, a classic sign of physical or provisioning failure. funiConnProfileEpdPpdIndex ties a connection to a specific early/partial packet discard profile, so cross-referencing it during congestion events helps confirm whether the correct discard policy is applied. This is a narrow, connection-level table rather than a full traffic-statistics MIB.

What Can Be Monitored

FUNI connection admin status
FUNI connection operational status
EPD/PPD profile assignment
frame-based ATM link state

OIDs

OID symbolic	OID numeric	Type	Access	Description
funi	1.3.6.1.4.1.326.1.16.6			write something interesting here
funiConnTable	1.3.6.1.4.1.326.1.16.6.1		not-accessible	Table of cross connections between FUNI and ATM connections
funiConnEntry	1.3.6.1.4.1.326.1.16.6.1.1		not-accessible	Entry in the FUNI/atm netmod crossconnect table
I32 funiConnFuniServiceIfIndex	1.3.6.1.4.1.326.1.16.6.1.1.1	Integer32	read-only	Interface index of the FUNI service this connection exists on
I32 funiConnFuniVpi	1.3.6.1.4.1.326.1.16.6.1.1.2	Integer32	read-only	VPI of this connection on the FUNI service
I32 funiConnFuniVci	1.3.6.1.4.1.326.1.16.6.1.1.3	Integer32	read-only	VCI of this connection on the FUNI service
I32 funiConnFabricServiceIfIndex	1.3.6.1.4.1.326.1.16.6.1.1.4	Integer32	read-only	This is the IfIndex associated with the pseudo atm service this connection is mapped to by the agent when this FUNI connection is created. This IfIndex can be converted to a BNP notation value through the IfIndexMapTable of the fore-switch MIB. This ifIndex will be stacked on top of the portIfIndex for a port. That BNP value can be used to establish a connection across the switching fabric by means of the FORE-switch MIB.
I32 funiConnFabricVpi	1.3.6.1.4.1.326.1.16.6.1.1.5	Integer32	read-only	This is the Fabric VPI of the ATM connection this FUNI connection is mapped to by the agent when this row is created. This VPI will be used to establish a connection across the switching fabric by means of the FORE-switch MIB
I32 funiConnFabricVci	1.3.6.1.4.1.326.1.16.6.1.1.6	Integer32	read-only	This is the Fabric VCI of the ATM connection this FUNI connection is mapped to by the agent when this row is created. This VCI will be used to establish a connection across the switching fabric by means of the FORE-switch MIB
ROW funiConnRowStatus	1.3.6.1.4.1.326.1.16.6.1.1.7	RowStatus	read-create	This object is used for dynamic creation of entries in this table. When the record is created, it is set to createAndWait, when the second hop of the connection is established across the fabric, this object's value is changed to go, which activates the IWF on the netmod
STR funiConnName	1.3.6.1.4.1.326.1.16.6.1.1.8	DisplayString	read-create	Symbolic name assigned to this connection by the operator
INT funiConnAdminStatus	1.3.6.1.4.1.326.1.16.6.1.1.9	INTEGER	read-create	Indicates whether the particular virtual circuit is operational.
INT funiConnOperStatus	1.3.6.1.4.1.326.1.16.6.1.1.10	INTEGER	read-only	Indicates the current operational status of a virtual circuit.
I32 funiConnProfileEpdPpdIndex	1.3.6.1.4.1.326.1.16.6.1.1.11	Integer32	read-create	The index of the EpdPpd Controller profile which contains: 1 ) Enable/disable the EPD for CLP=0 cells for a specific connection; 2 ) Enable/disable the EPD for CLP=1 cells for a specific connection; 3 ) Enable/disable the PPD for CLP=1 cells for a specific connection.
funiIfExtTable	1.3.6.1.4.1.326.1.16.6.2		not-accessible	This table incorporates the information pertinent to FUNI services, which is not part of the standard FUNI mib.

I32 funiIfExtProfileFuniIndex	1.3.6.1.4.1.326.1.16.6.2.1.1	Integer32	read-write	This is index of the FUNI profile this service is supposed to be using. This index should be used as a key in profileFuniTable
I32 funiIfExtProfileServiceIndex	1.3.6.1.4.1.326.1.16.6.2.1.2	Integer32	read-write	This is index of the Generic Service profile this service is supposed to be using. This index should be used as a key in profileGenServiceTable
INT funiIfExtStatsMonitor	1.3.6.1.4.1.326.1.16.6.2.1.3	INTEGER	read-write	This object specifies whether statistics are to be counted at a service level, this includes service and connection statistics. When the state changes from enabled to disabled all the related statistics will be frozen at their current value. When the state changes from disabled to enabled then all related statistics will be reset (zeroised). Note that this Monitor is overriden by the netmod level nmFramStatsMonitor. Refer to fore-fram.mib for more details.

Note that the value of this object may be obtained in different ways, e.g., by manual configuration, or through ILMI interaction with the neighbor system.This object is a mirror of atmInterfaceMyNeighborIpAddress from the ATM MIB
TIK funiIfExtStatsEnabledTimeStamp	1.3.6.1.4.1.326.1.16.6.2.1.5	TimeTicks	read-only	This object reflects the point in time, with reference to sysUpTime, either when funIfExtStatsMonitor is set to enabled or when nmFramStatsMonitor is set to enabled. The time will reflect the last StatsMonitor to be enabled. The timestamp provides a starting timestamp for the current statistics that are being counted.
INT funiIfExtSigStatus	1.3.6.1.4.1.326.1.16.6.2.1.6	INTEGER	read-only	This object indicates whether there exists a FUNI signalling instance associated with the FUNI service. The possible value for this object is summarized as follows: FUNI Signalling Support Possible Value of this object =============================================================== disabled nonexist(2) _______________________________________________________________ enabled exist(1) nonexist(2) _______________________________________________________________
