    ASED A NAGEMEN T Parameter Default Description The maximum time (in secon ds) a device can wait (Message) without receiving a configuration message before attempting to reconfigur e. All device ports (except for designated ports) should r eceive configuration messages at regular intervals. Any port that ages out STA information (provided in the last configuration message) becomes the designated port for the attached LAN.

  • Page 125: Advanced Topics

    HAPTER 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 126 DVANCED OPICS Once a stable network topology has been established, all bridges listen for Hello BPDUs (Bridge Protocol Data Units) transmitted from the Root Bridge. If a bridge does not get a Hello BPDU after a predefined interval (Maximum Age), the bridge assumes that the link to the Root Bridge is down.

  • Page 127: Virtual Lans

    DVANCED OPICS Virtual LANs Switches do not inherently support broadcast domains, which can lead to broadcast storms in large networks that handle a lot of IPX traffic. In conventional networks with routers, broadcast traffic is split up into separate domains to confine broadcast traffic to the originating group and provide a much cleaner network environment.

    DVANCED OPICS • End stations can belong to multiple VLANs • Passing traffic between VLAN-aware and VLAN-unaware devices • Two-level priority tagging Assigning Ports to VLANs Before enabling VLANs for the switch, you must first assign each port to the VLAN group(s) it will participate in. (By default all ports are assigned to VLAN 1 as untagged ports.) Add a port as a tagged port (that is, a port attached to a VLAN-aware device) if you want it to carry traffic for one or more VLANs and the device at the...

  • Page 129: Port Overlapping

    DVANCED OPICS Port Overlapping Port overlapping can be used to allow access to commonly shared network resources among different VLAN groups, such as file servers or printers. Note that if you implement VLANs which do not overlap, but still need to communicate, you must connect them using a router or Layer 3 switch (such as the SMC6716L3).

  • Page 130: Forwarding Traffic With Unknown Vlan Tags

    DVANCED OPICS Forwarding Traffic with Unknown VLAN Tags Up to 2048 VLANs are supported by the IEEE 802.1Q protocol, but this switch only supports 16 VLANs. Therefore, if this switch is attached to any device that forwards frames with unknown VLAN tags, or to endstations which issue VLAN registration requests for unknown VLANs, this traffic will be dropped.
  • Page 131 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, to support IP multicasting across the Internet.
