  • Derived vlan mapping technique
    Publication number: 20010005369
    Abstract: A method of operating a switch for frames in a computer network uses one or more indicia of frame type designation found in the received frame to derive a virtual local area network (derived VLAN) value. Also, an indicia of the receiving port may be used in constructing the derived VLAN value. The switch then uses the derived VLAN value in making forwarding decisions. Broadcast domains in the computer network may then be controlled by forwarding in response to the derived VLAN value.

  • Derived VLAN mapping technique
    Patent number: 6208649
    Abstract: A derived virtual local area network (VLAN) mapping technique enables centralized control of broadcast domains by a switch capable of supporting different protocols carried within frames that are distributed throughout a computer internetwork. Associated with each incoming frame received at the switch are characteristics such as protocol type and/or subnet information, and associated with each input port of the switch are characteristics such as VLAN and/or index values. Utilizing certain of these characteristics, a derived VLAN value is generated that allows users to create arbitrary VLAN domains and reduce broadcast traffic received by stations of the domains.
