Description: Provides management objects for monitoring the switch fabric components of the Cisco 12000 (GSR) series router chassis.
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 CISCO-FABRIC-C12K-MIB?
CISCO-FABRIC-C12K-MIB manages the internal switch fabric of the Cisco 12000 series (GSR) router chassis, an NxN non-blocking crossbar architecture connecting line cards through a central scheduler. It exposes configuration objects for fabric mode and scheduler settings along with per-link state tables describing the health of each fabric-to-fabric and fabric-to-line-card connection. The MIB is squarely focused on monitoring hardware status: it reports fabric link state, grant/request cell counts, and FIFO occupancy that reveal congestion, link failures, or scheduler malfunctions inside the chassis backplane. It is a Cisco-proprietary MIB specific to the c12000 fabric architecture and has no dependency on general IETF standards. It is deployed exclusively on Cisco 12000/GSR series core routers, where CISCO-FABRIC-C12K-MIB SNMP monitoring gives operators visibility into internal fabric card health.
IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-FABRIC-C12K-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.
Supported Devices
- Cisco 12000 series (GSR) routers
Monitoring Examples
An operator would poll cfcGenericFabToFabTable, indexed per fabric-to-fabric connection, reading cfcGenericFabToFabState to confirm each internal link is up, alongside cfcGenericFabToFabGrantPEs and cfcGenericFabToFabRequestPEs to check for balanced cell scheduling. A persistent mismatch between granted and requested PEs, or a nonzero cfcGenericFabToFabCellFifoPEs backlog, would indicate fabric congestion or a failing crossbar path. The related cfcGenericFabFrFabTable exposes similar state for fabric-card-to-line-card links, useful for isolating a faulty card.
What Can Be Monitored
- fabric configuration mode
- master scheduler state
- fabric-to-fabric link state
- grant/request cell counts
- cell FIFO occupancy
- fabric card link state

How to Use in IPNetwork Monitor
Example using cfcGenericFabToFabGrantPEs OID:
Select a Cisco 12000 series (GSR) router (legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cfcGenericFabToFabGrantPEs into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. It reports the count of parity errors detected by the ToFabFIA on the grant lines to SCA. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases between polls, since a rising count of errors, failures, or discards often points to a real underlying problem. Click Finish to create the monitor; you can adjust any parameter later.

| ciscoFabricC12kMIB | 1.3.6.1.4.1.9.9.281 | Cisco Fabric MIB module for c12000 series of routers. This MIB module is used for managing/tracking the c12000 fabric entities and fabric related configuration, status and statistics information. C12000 fabric architecture is based on NxN non-blocking crossbar switch fabric, where N stands for the maximum number of LCs that can be supported in the chassis (this includes the RP). The connections through the switch fabric is controlled by a scheduler (CSC), the CSC accepts transmission requests from line cards, issues grants to access the fabric, and provides a reference clock to all the cards in the system to synchronize data transfer across the crossbar. Some of the error status objects in the MIB are read-clear, that is the value of the object is cleared on a query of the object. Details about the various fabric related attributes specified in the MIB could be found at following link, http://www.cisco.com/warp/public/108/hwts_12000_22281.html Acronyms and terms used in the MIB module: GSR - Gigabit Switch Router. RP - Route Processor. LC - Line Card. SFC - Switch Fabric Card. CRC - Cyclic Redundancy Check. CSC - Clock Scheduler Card. CiscoCell - The unit of data that is exchanged between line cards through the switch fabric. FIA - Fabric Interface Asic, this Asic resides on the line card and is used to interface line card and switch fabric. ToFabFIA - Represents the ToFabric FIA, FIA which transmits data from the line card to the fabric. FrFabFIA - Represents the From Fabric FIA, FIA which receives data from the fabric. SCA - Scheduler Control Asic, this Asic resides on each CSC and is used to arbitrate among the line card requests to transmit CiscoCells through the switch fabric. Xbar - Crossbar Switch Asic, this Asic resides on each fabric card and provides the functionality of a crossbar switch. SLI - Serial Link interface block, this block resides on the FIA on the line cards and the Xbar and SCA on the switch fabric. The functionality of SLI is to interface the linecards and fabric cards. BMA - Buffer Manager Asic, this Asic is located on a Pre OC-192 linecard. It provides the packet buffering and buffer queue management. MCC - Memory Communication Controller Asic, this Asic is located on a OC-192 linecard and is an enhanced packet buffer Asic. MCC captures the data and control path information for packets destined to all line cards in the system. On the receive side MCC interfaces with the Rx Asic where the packets are looked up and sent to the MCC for buffering. On the transmit side it interfaces with the ToFabFIA where packets arrived from MCC will be segmented into CiscoCells before being sent across the fabric. CSAR - Cisco Cell Segmentation And Reassembly, The name of an FPGA used on the RP which handles traffic between the processor and switch fabric. Request - A signal sent by a FIA (on a line card) to the SCA (on Master CSC) requesting a switch connection to a output linecard as an intent to transmit CiscoCells across. Grant - A signal sent by the SCA to a FIA (on a line card) granting a switch connection which was requested by the FIA. SRAM - Static Random Access Memory. LOS - Loss Of Signal. FPGA - Field Programmable Gate Array. | ||
