CISCO-FABRIC-C12K-MIB: View SNMP OID List / Download MIB

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.

This notification is generated when master scheduler on the system changes. It typically indicates the switchover of the scheduler card. cfcGenericGlobalFabMasterSched represents the entPhysicalIndex of the new master scheduler card, while entPhysicalName represents the entity physical name of the card. The case of all scheduler cards going down would be represented by a value 0 for the cfcGenericGlobalFabMasterSched and noSuchInstance for the entPhysicalName.

This object gives the current bandwidth and redundancy configuration of fabric in the system.
