    Introduction The 9T122-08 MicroLAN™ Switch Extension Module, shown in Figure 1-1, is a three port Token Ring switch module. This module supports two separate Token Rings with four lobe connections each, and an interface to the FNB backplane. Each front panel Token Ring also supports Ring-in/Ring-out connections by using plug-in Token Ring Port Interface modules (TPIMs).
  • Page 10 Introduction Management Information Base (MIB) Support The 9T122-08 module provides MIB support including: • IETF MIB II (RFC 1213) • IETF Bridge MIBs (RFC 1493 and 1525) • IEEE 802.5 Token Ring MIB (RFC 1231) • Cabletron Enterprise MIBs For a complete list of supported MIBs, refer to the release notes provided in the NOTE module package.

    Figure 3-1 is a block diagram of the module. The two front panel rings function as individual networks, each with four ports. Bridging may occur between these two rings and/or to any other SmartSwitch 9000 module via the Flexible Network Bus.

  • Page 22: Transparent Bridging (Provided Between All Three Interfaces)

    Operation Source Route Transparent Packets Transparent Bridging Transparent Bridging is accomplished by building a Source Address Table (SAT) from source MAC/physical addresses and using the SAT to make forwarding decisions. The 9T122-08 prevents unnecessary network traffic from passing through the module by implementing two separate filtering processes —...

  • Page 23: Source Route Bridging (Provided Only Between Front Panel Rings)

    Source Route Bridging Source Route Bridging operates by transmitting frames over a designated route. Unlike Transparent Bridging, all devices in a Source Route Bridged (SRB) network “know” the locations of other stations within the network. Using a portion of the MAC frame header known as the RIF (Routing Information Field), the source device determines the route for the frames it sends.

    400 Mbps of data bandwidth. These FDDI networks are 100% ANSI FDDI-compliant supporting SMT (version 7.3), MAC, PHY, and PMD standards. This allows the FNB to traverse multiple SmartSwitch 9000 hubs, or connect to any ANSI FDDI-compliant device, through standard A/B port connections, using the FDDI repeater module.

    SMB-10 Bus The SMB-10 is a 10Mbs management bus located within the SmartSwitch 9000 which is also used for inter-chassis communication of modules as well as serving as an out-of-band management channel into the SmartSwitch 9000. The SMB-10 is externalized from the chassis via an optional Ethernet Port Interface Module (EPIM) located on the front of the Environmental Module.
