SIB

Both the PTX5000 and PTX3000 switch fabric are engineered with a 9-slot all-active SIB architecture. In the case of a SIB failure, the remaining eight active SIBs maintain enough switch fabric capacity to support full line packet performance per slot- 24Tbps of total system capacity for the PTX5000 and 8Tbps of total system capacity for the PTX3000.
