In the Ultra Transcenders books

2V0-17.25

Each book explains segment in context, with comparison tables and the common traps.

Terms in this definition

• L2

  Layer 2 of the OSI model, the data link layer of frames, VLANs and MACs. An NSX segment is one broadcast domain at this layer.

• NSX

  Software that handles networking and security across VCF, covering firewalling, load balancing, NAT, VPCs, overlay segments and Tier-0/1 gateways.

• Physical

  Describes the concrete, real-world parts that put a logical architecture into effect.

• VLAN

  Layer 2 broadcast domain tagged using 802.1Q. In VCF they carry TEP, vSAN, vMotion and management traffic, and NSX can back segments with them.

• DHCP relay agent

  A device, either a router or a server, that picks up DHCP broadcasts on its local network segment and passes them to a DHCP server elsewhere.

• transport zone

  Decides in NSX which VMs may attach to a given segment, by defining the Edge and host nodes it spans; every one is either VLAN or overlay type.
