Objective 4.4 – Expand Transport Zone to Include New Cluster(s)

Knowledge

• Explain the function of a Transport Zone
  
  • A transport Zone defines a collection of ESXi hosts that can communicate with each other across a physical network.
  • It extends across one or more ESXi clusters, and in a loose sense defintes the span of logical switches.
• Add a Transport Zone
  • Log in to the vSphere Web Client.
  • Navigate to “Networking & Security” and “Installation”.
  • Click “Logical Network Preparation” and then click “Transport Zones”.
  • Click the “New Transport Zone” icon.
  • In the New Transport Zone dialog box, type a name and description for the transport zone.
  • Depending on whether you have a controller node in your environment, or you want to use multicast addresses, select the control plane mode.
    • Multicast: Multicast IP addresses on physical network are used for the control plane. This mode is recommended only when you are upgrading from older VXLAN deployments. Requires PIM/IGMP on physical network.
    • Unicast : The control plane is handled by an NSX controller. All unicast traffic leverages headend replication. No multicast IP addresses or special network configuration is required.
    • Hybrid : The optimized unicast mode. Offloads local traffic replication to physical network (L2 multicast). This requires IGMP snooping on the first-hop switch, but does not require PIM. First-hop switch handles traffic replication for the subnet.
  • Select the clusters to be added to the transport zone.
  • Click OK.
• Expand/Contract a Transport Zone
  • Expand:
    • Log in to the vSphere Web Client.
    • Navigate to “Networking & Security” and “Installation”.
    • Click “Logical Network Preparation” and then click “Transport Zones”.
    • Click a transport zone.
    • In Transport Zones Details, click the Add Cluster icon.
    • Select the clusters you want to add to the transport zone.
    • Click OK.
  • Contract
    • Log in to the vSphere Web Client.
    • Navigate to “Networking & Security” and “Installation”.
    • Click “Logical Network Preparation” and then click “Transport Zones”.
    • Double-click a transport zone.
    • In Transport Zones Details, click the Remove Clusters icon.
    • Select the clusters you want to remove.
    • Click OK.
• Edit a Transport Zone
  • Log in to the vSphere Web Client.
  • Navigate to “Networking & Security” and “Installation”.
  • Click “Logical Network Preparation” and then click “Transport Zones”.
  • Double-click a transport zone.
    The Summary tab displays the name and description of the transport zone as well as the number of logical switches associated with it. Transport Zone Details displays the clusters in the transport zone.
  • Click the Edit Settings icon in the Transport Zone Details section to edit the name or description of the transport zone.
  • Click OK.
• Change the Control Plane mode for a Transport Zone
  • Log in to the vSphere Web Client.
  • Navigate to “Networking & Security” and “Installation”.
  • Click “Logical Network Preparation” and then click “Transport Zones”.
  • Double-click a transport zone.
    The Summary tab displays the name and description of the transport zone as well as the number of logical switches associated with it. Transport Zone Details displays the clusters in the transport zone.
  • Click the Edit Settings icon in the Transport Zone Details section to edit the control plane mode of the transport zone.
  • Select Migrate existing Logical Switches to the new control plane mode to change the control plane more for existing logical switches linked to this transport zone. If you do not select this check box, only the logical switches linked to this transport zone after the edit is done will have the new control plane mode.
  • Click OK.
