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

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
