  • Page 143: Advanced Topics

    HAPTER DVANCED OPICS This TigerSwitch 10/100 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 144: 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 145: 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 146: 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 147: 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 148: Forwarding Traffic With Unknown Vlan Tags

    DVANCED OPICS Forwarding Traffic with Unknown VLAN Tags This switch only supports 256 VLANs with VLAN IDs ranging from 1 to 2048, but the IEEE 802.1Q VLAN standard allows for VLAN IDs from 1 to 4094. Therefore, if this switch is attached to endstations that issue VLAN registration requests, it will have to forward unknown VLAN tags.

  • Page 149: 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 SMC6716L3) or a router.

  • Page 150: Igmp Protocol

    DVANCED OPICS the group registration information, and configures multicast filters accordingly. IGMP Snooping generates no additional network traffic, allowing you to significantly reduce the multicast traffic passing through your switch. IGMP Protocol The Internet Group Management Protocol (IGMP) runs between hosts and their immediately neighboring multicast router/switch.
