    2. Switch Overview This chapter explains how the CrossFire 8730 Fast Ethernet Translation Switch improve network performance. How the CrossFire 8730 Works The switch contains the following main elements, as listed below: • Switching Bus—the architecture of the switch centers around the AXIS bus, a 520 Mbps switching fabric through which all switched ports communicate.

  • Page 30: Figure 4. Multiple Conversations Through A Crossfire 8730

    A single segment can be dedicated to a single host or shared by several. To optimize throughput, high-speed servers can be given dedicated switch ports. By transporting Token-Ring packets simultaneously, the CrossFire 8730 boosts overall network throughput. CrossFire 8730 Switch Reference Guide, DOC-7047 v. 1.1...

  • Page 31: Address Management

    Fast Ethernet port must know all the active addresses in the network. Multiple Bridging Modes The CrossFire 8730 supports four different switching modes to provide maximum flexibility in all installation environments. The switching modes are Source Route Switching (SRS), Source Route Bridging (SRB), Source Route Transparent (SRT) and SRT/SRB.
  • Page 32 Parallel paths are eliminated via the IEEE 802.1D Spanning Tree Protocol. Source Route Bridging (SRB) The BRF acts as a multiport Source Route Bridge between CRFs with the following characteristics: CrossFire 8730 Switch Reference Guide, DOC-7047 v. 1.1 Switch Overview...
  • Page 33 The benefit of the SRT/SRB mode is that it allows part of the network to be run in SRT mode to accommodate applications that do not support source routing, while still supporting duplicate MAC addresses on a number of SRB ports (for example, for SNA gateway applications).

  • Page 46: Token-Ring

    RI/RO-Like Connection On CrossFire 8730, a RI/RO-like connection is available on ports 19 and 20. This feature allows the switch to connect to CAU/LAM systems using the RI/RO connections thus providing a RI/RO-like functionality. This enables the switch to be easily installed in existing Token-Ring networks.

  • Page 47: Transmission Priority Queues

    Any errors, such as attaching port 19 or 20 to a normal MAU port when the CrossFire 8730 port has been configured for RI/RO, will cause a complete disruption of the ring to which the port is attached.

    Spanning Tree Protocol Support The CrossFire 8730 supports the spanning tree protocols most often used in both Ethernet and Token-Ring topologies. The switch supports IEEE 802.1D Spanning Tree for all Ethernet ports, and both IEEE 802.1D Spanning Tree and IBM Spanning Tree Protocols for Token-Ring ports.
