  • Page 29: Chapter 3 Operation

    Chapter 3 Operation The 9G426-02 module is a two port Gigabit Ethernet device. Two front panel GPIMs support Ethernet connectivity through a Fiber channel and are capable of providing MMF connectivity through SC connections. As shown in Figure 3-1, Gigabit Network Interface Blocks (GNIBs) convert data packets received from any of the GPIMs into a canonical frame format before forwarding to the SmartSwitch ASIC, while the Internal Network Bus Network Interface Block (INB NIB) converts data packets received from the INB into a...

  • Page 30: Smartswitch Asic

    Operation All data packets destined for a front panel port, the INB, or the i960 are converted into the canonical format before forwarding to the SmartSwitch ASIC. Network Interface Blocks (NIBS) check for valid data packets entering the system. If an errored data packet is found, the SmartSwitch ASIC flags the error and does not forward the errored data packet to any outbound ports.
  • Page 31 Operation A VLAN is a local area network of endpoints having full connectivity (sharing broadcast, multicast, and unicast packets) independent of any particular physical or geographical location. In other words, endpoints that share a virtual LAN appear to be on a single LAN segment regardless of their actual location. Changes to VLANs (e.g., moving nodes) are accomplished via software , which reduces network management time and expense.

  • Page 32: Vlan Domains

    Operation VLAN Domains VLAN domains consist of groups of interconnected VLAN switches separated by routing devices. Figure 3-3 shows such an arrangement. Each group of switches constitutes a VLAN domain. Routing Device VLAN Domain VLAN Domain SFS Network SFS Network VLAN Switch VLAN Switch VLAN Switch...

  • Page 33: Securefast Vlan Switches

    Operation SecureFast VLAN Switches SecureFast VLAN (SFVLAN) switches are connection-oriented internetworking devices. These devices use source address/destination address (SA/DA) pairs along with embedded layer 3 virtual routing services to provide address resolution and call processing. In a connection-oriented network, path determination is accomplished through signaling performed at call setup time.

  • Page 34: System Management Buses

    Operation System Management Buses There are two management channels within the MMAC-Plus system: the SMB-1 and the SMB-10. These buses provide side-band management and inter-module management communication. SMB-1 Bus The SMB-1 is a 1Mbs management bus located within the MMAC-Plus. This bus is utilized by all diagnostic controllers in the system including connectivity modules, power supply modules and the environmental module.

  • Page 35: Dc/Dc Converter

    Operation DC/DC Converter The DC/DC converter converts the 48 VDC on the system power bus to the necessary operating voltages for its host network services module. The diagnostic controller monitors and controls the operation of the DC/DC converter. INB Interface The INB Backplane is designed to transport fixed length data blocks between modules in the MMAC-Plus using a Time Division Multiplexing (TDM) design.

  • Page 36: Monarch/Slave Mmac-Plus Modules

    Operation ITDM RAM Allocation (Level 1) This level guarantees access to the backplane. When a module requests access to the backplane, it will get access to it when it's slot number is placed onto the bus. This will ensure predicted or predetermined access to the backplane. Round Robin Arbitration (Level 2) This level makes use of idle time slices.
