Abstract
One embodiment of the present invention provides a switch. The switch includes a forwarding mechanism and a control mechanism. During operation, the forwarding mechanism forwards frames based on their Ethernet headers. The control mechanism operates the switch in conjunction with a separate physical switch as a single logical switch and assigns a virtual switch identifier to the logical switch, wherein the virtual switch identifier is associated with a link aggregation group.
Claims20
A switch, comprising:
- a forwarding mechanism configured to forward frames based on their Ethernet headers;
- and
- a control mechanism configured to operate the switch in conjunction with a separate physical switch as a single logical switch and assign a virtual switch identifier to the logical switch, wherein the virtual switch identifier is associated with a link aggregation group.
A method, comprising:
- forwarding frames received at a switch based on their Ethernet headers;
- operating the switch in conjunction with a separate physical switch as a single logical switch;
- and
- assigning a virtual switch identifier to the logical switch, wherein the virtual switch identifier is associated with a link aggregation group.
A switch means, comprising:
- a forwarding means for forwarding frames based on their Ethernet headers;
- a control means for operating the switch in conjunction with a separate physical switch as a single logical switch and assigning a virtual switch identifier to the logical switch, wherein the virtual switch identifier is associated with a link aggregation group.
