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

Details about the various fabric related attributes 
specified in the MIB could be found at following link,

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
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
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 
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.
