11.3. Creating Logical Networks

11.3.1. Creating a New Logical Network in a Data Center or Cluster

Summary
Create a logical network and define its use in a data center, or in clusters in a data center.

Procedure 11.1. Creating a New Logical Network in a Data Center or Cluster

  1. Use the Data Centers or Clusters resource tabs, tree mode, or the search function to find and select a data center or cluster in the results list.
  2. Click the Logical Networks tab of the details pane to list the existing logical networks.
    • From the Data Centers details pane, click New to open the New Logical Network window.
    • From the Clusters details pane, click Add Network to open the New Logical Network window.
  3. Enter a Name, Description, and Comment for the logical network.
  4. Optionally select the Create on external provider check box. Select the External Provider from the drop-down list and provide the IP address of the Physical Network.
    If Create on external provider is selected, the Network Label, VM Network, and MTU options will be removed.
  5. Enter a new label or select an existing label for the logical network in the Network Label text field.
  6. Optionally enable Enable VLAN tagging.
  7. Optionally disable VM Network.
  8. Set the MTU value to Default (1500) or Custom.
  9. From the Cluster tab, select the clusters to which the network will be assigned. You can also specify whether the logical network will be a required network.
  10. If Create on external provider is selected, the Subnet tab will be visible. From the Subnet tab, enter a Name, CIDR, and Gateway address, and select an IP Version for the subnet that the logical network will provide. You can also add DNS servers as required.
  11. From the vNIC Profiles tab, add vNIC profiles to the logical network as required.
  12. Click OK.
Result
You have defined a logical network as a resource required by a cluster or clusters in the data center. If you entered a label for the logical network, it will be automatically added to all host network interfaces with that label.

Note

When creating a new logical network or making changes to an existing logical network that is used as a display network, any running virtual machines that use that network must be rebooted before the network becomes available or the changes are applied.
