3-1 Chapter 3 Operation The 9T425-16, 9T427-16, and 9T428-16 SmartSwitch 9000 Modules provide connectivity between the front panel T oken Rings and the INB2 backplane. SmartSwitch 9000 modules connect to either the Internal Network Bus (INB) or the Flexible Network Bus (FNB) bus.
Operation 3-2 Figure 3-1. 9T425-16, 9T427-16, and 9T428-16 Block Dia gram All data packets destined for a front panel port, the INB, or the i960 ar e converted into the canonical format before forwar ding to the SmartSwitch 9000 ASIC. Network Interface Blocks (NIBs) check for valid data packets entering the system.
3-3 Operation Switching The 9T425-16, 9T427-16, and 9T428-16 operate as a Source Route T ranslational (SR-TB) switch. They provide translation to transpar ent frames. For information on conÞguring the switching function, see the addendum to the SmartSwitch 9000 Local Management User Õs Guide, containing information speciÞc to this model.
Operation 3-4 Sour ce Route and Sour ce Route T ranslational Switching In SR (Source Routing) and SR T (Source Route and T ransparent) modes, the received SR packets ar e stripped of their RIF during the translation to canonical frame format.
3-5 Operation Spanning T ree Algorithm is a hierarchy (or tr ee) of priorities that bridges establish between themselves. This hierarchy guarantees that primary and r edundant data paths are clearly deÞned at all times, so that the network is continuously available to users.
Operation 3-6 System Diagnostic Contr oller This diagnostic controller is composed of a Z-80 micr oprocessor and its supporting logic. The diagnostic controller is designed to contr ol the power-up se.
3-7 Operation learning. When operating in SecureFast Switch mode, all Þltering/forwar ding decisions are made based on a DA-SA pair and its receive port. The SmartSwitch 9000 hub can support modules operating in traditional switch mode and SecureFast Switch mode simultaneously .
