There is also an SNMP-based management agent embedded on the main board. This agent supports both in-band and out-of-band access for managing the switch.

  • Page 18: About The Tigerswitch 10/100

    10/100 BOUT THE IGER WITCH Switch Architecture The TigerSwitch is perfect for moving workgroups from conventional 10 Mbps Ethernet to multiple-segment 100 Mbps Fast Ethernet. This switch delivers dedicated 100 Mbps links to each attached LAN segment (independent collision domain) or to any PC attached directly to the switch, all with conventional cabling and adapters.

  • Page 19: Description Of Hardware

    ESCRIPTION OF ARDWARE Description of Hardware Ethernet Ports The base unit contains 24 10BASE-T / 100BASE-TX ports. It also has two slots on the rear panel for optional 100BASE-FX or Gigabit uplink modules. The 100BASE-FX modules have one single-mode (SC-type) or multimode (SC-type) port. The Gigabit modules have one 1000BASE-SX (SC-type), 1000BASE-LX (SC-type), or 1000BASE-T (RJ-45) port.

  • Page 22: Spanning Tree Protocol

    10/100 BOUT THE IGER WITCH Spanning Tree Protocol The TigerSwitch 10/100 supports IEEE 802.1D Spanning Tree Protocol. This protocol adds a level of fault tolerance by allowing two or more redundant connections to be created between a pair of LAN segments. When there are multiple physical paths between segments, this protocol will choose a single path and disable all others to ensure that only one route exists between any two stations on the network.

  • Page 23: Multicast Switching

    ESCRIPTION OF ARDWARE Multicast Switching Specific multicast traffic can be assigned to its own VLAN to ensure that it does not interfere with normal network traffic and to guarantee real-time delivery by setting the required priority level for the designated VLAN. The switch uses IGMP Snooping and IGMP to manage multicast group registration.

    HAPTER ETWORK LANNING Introduction to Switching A network switch allows simultaneous transmission of multiple packets via non-crossbar switching. This means that it can partition a network more efficiently than bridges or routers. The switch has, therefore, been recognized as one of the most important building blocks for today’s networking technology.
