VLT domain - The domain includes VLT peer devices, VLT interconnects, and all port-channels in the VLT connected to the attached devices. It is also the configuration mode that you must use to assign VLT global parameters.
VLT interconnect (VLTi) - The link between VLT peer switches used to synchronize operating states.
VLT peer device - A pair of devices connected using a dedicated port-channel—the VLTi. You must configure VLT peers separately.
Discovery interface - Interfaces on VLT peers in the VLT interconnect (VLTi) link.
VLT MAC address - Unique MAC address that you assign to the VLT domain. A VLT MAC address is a common address in both VLT peers. If you do not configure a VLT MAC address, the primary peer's MAC address is used as the VLT MAC address across both peers.
VLT node priority - The priority based on which the primary and secondary VLT nodes are determined. If priority is not configured, the VLT node with the lowest MAC address is elected as the primary VLT node.
VLT port-channel - A combined port-channel between an attached device and the VLT peer switch.
