Dell EMC SmartFabric OS10 User Guide Release 10.5.1

Terminology

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 MAC address of the primary peer 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 VLT peer switches.

VLT port channel ID

Groups port channel interfaces on VLT peers into a single virtual-link trunk connected to an attached device. Assign the same port channel ID to port channel interfaces on both peers that you bundle together.

Orphan ports

Ports that are not part of the VLT port channel but members of the spanned VLANs. The term spanned VLAN refers to a VLAN that is configured on both the VLT peers.
