Dell SmartFabric OS10 Glossary
V
- Virtual extensible LAN (VXLAN)
- A type of network virtualization overlay that encapsulates a tenant payload into IP UDP packets for transport across the IP underlay network.
- Virtual fabric (vfabric)
- A fabric that divides a physical fabric into logical fabrics.
- Virtual LANs (VLANs)
- A group of devices on one or more LANs that are configured to communicate as if they were attached to the same wire, when in fact they are located on a number of different LAN segments.
- Virtual Link Trunking (VLT)
- A L2 aggregation protocol used between an end device such as a server and two or more connected network devices. VLT helps to aggregate ports terminating on multiple switches.
- Virtual network
- An overlay network in the L2 flooding domain.
- Virtual network identifier (VNID)
- A 16-bit ID number that identifies a virtual network in OS10.
- Virtual Router Redundancy Protocol (VRRP)
- A protocol that eliminates a single point of failure in a statically routed network.
- Virtual Routing and Forwarding (VRF)
- A mechanism to partition a physical router into multiple virtual routers.
- Virtual Teletype (VTY)
- A command line interface (CLI) created on a switch to facilitate a connection through Telnet.
- Virtual-network interface
- A router interface that connects a virtual network bridge to a tenant VRF routing instance.
- VLT domain
- A domain that includes VLT peer devices, VLT interconnects, and all port channels in the VLT connected to the attached devices. You must use this configuration mode to assign VLT global parameters.
- VLT interconnect (VLTi)
- The link between VLT peer switches that synchronizes operating states.
- VLT MAC address
- A 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 peer device
- A pair of devices connected using a dedicated port channel—the VLTi. You must configure VLT peers separately.
- VLT port channel
- A link aggregation technology that combines two or more physical interfaces into a single logical interface.
- VRRP authentication
- A process that allows trusted routers to participate in VRRP processes.
- VXLAN Network Identifier (VNI)
- A 24-bit ID number that defines the broadcast domain.
- VXLAN Tunnel Endpoint (VTEP)
- A switch with connected end hosts that are assigned to virtual networks. The virtual networks map to VXLAN segments. Local and remote VTEPs perform encapsulation and de-capsulation of VXLAN headers for the traffic between end hosts. A VTEP is also known as a network virtualization edge.
