    NTRODUCTION VERVIEW This Fast Ethernet Switch is an intelligent multilayer switch (Layer 2/3/4) with 24 10/100BASE-TX ports, two 10/100/1000BASE-T combination ports that are shared with SFP transceiver slots (Ports 25-26), and two SFP slots. This switch can easily tame your network with full support for Spanning Tree Protocol, Multicast Switching, Virtual LANs, and IP routing.
  • Page 24 | Introduction HAPTER Overview WITCH RCHITECTURE This Fast Ethernet switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. For communications between different VLANs, this switch uses IP routing.

  • Page 34: Figure 7: Ip Routing For Unicast Traffic

    | Network Planning HAPTER Application Examples SING AYER OUTING VLANs can significantly enhance network performance and security. However, if you use conventional routers to interconnect VLANs, you can lose most of your performance advantage. This device is a routing switch that provides wire-speed routing, which allows you to eliminate your conventional IP routers, except for a router to handle non-IP protocols and a gateway router linked to the WAN.
