  • Page 145: Advanced Topics

    HAPTER DVANCED OPICS This TigerSwitch 100 supports Layer 2 switching and other advanced features, which are described in this chapter. Layer 2 Switching When a frame enters a port, its destination MAC address is checked in the address database to see which port leads to this destination.

  • Page 146: Spanning Tree Algorithm

    DVANCED OPICS Spanning Tree Algorithm The Spanning Tree Algorithm (that is, the STA configuration algorithm as outlined in IEEE 802.1D) can be used to detect and disable network loops, and to provide link backup. This allows the switch to interact with other bridging devices (including STA-compliant switches, bridges or routers) in your network to ensure that only one route exists between any two stations on the network.

  • Page 147: Virtual Lans

    DVANCED OPICS The following figure gives an illustration of how the Spanning Tree Algorithm assigns bridging device ports. Virtual LANs Switches do not inherently support broadcast domains, which can lead to broadcast storms in large networks that handle a lot of IPX or NetBeui traffic.

  • Page 148: Assigning Ports To Vlans

    DVANCED OPICS VLANs provide greater network efficiency by reducing broadcast traffic, but also allow you to make network changes without having to update IP addresses or IP subnets. VLANs inherently provide a high level of network security, since traffic must pass through a Layer 3 switch or a router to reach a different VLAN.

  • Page 149: Port Overlapping

    DVANCED OPICS Port-based VLANs are tied to specific ports. The switch’s forwarding decision is based on the destination MAC address and its associated port. Therefore, to make valid forwarding and flooding decisions, the switch learns the relationship of the MAC address to its related port—and thus to the VLAN—at run-time.

  • Page 150: Connecting Vlan Groups

    DVANCED OPICS Connecting VLAN Groups The switch supports intra-VLAN communication using wire-speed switching. However, if you have devices in separate VLANs that must communicate, and it is not practical to include these devices in a common VLAN, then the VLANs can be connected via a Layer 3 switch (such as the SMC6724L3) or a router.

  • Page 151: Igmp Snooping

    DVANCED OPICS nodes join or leave multicast groups. A switch or router can then easily determine which ports contain group members and send data out to those ports only. This procedure is called multicast filtering. The purpose of multicast filtering is to optimize a switched network’s performance, so multicast packets will only be forwarded to those ports containing multicast group hosts or multicast routers/switches instead of flooding to all ports in the...

  • Page 152: Class-Of-Service (Cos) Support

    DVANCED OPICS Based on the group membership information learned from IGMP, a router/switch can determine which (if any) multicast traffic needs to be forwarded to each of its ports. At Layer 3, multicast routers use this information, along with a multicast routing protocol such as DVMRP, to support IP multicasting across the Internet.

  • Page 153: Port Trunks

    DVANCED OPICS Port Trunks Ports can be combined into an aggregate link to increase the bandwidth of a network connection or ensure fault recovery. You can group ports into trunks that consist of two, three or four ports, creating an aggregate bandwidth up to 8 Gbps when grouping multiple Gigabit ports.

    DVANCED OPICS event manager, log manager, MIB browser, RMON analysis tools, and device management modules. SMC also provides optional plug-in device management modules for HP OpenView. Remote Monitoring Remote Monitoring (RMON) provides a cost-effective way to monitor large networks by placing embedded or external probes on distributed network equipment (hubs, switches or routers).
