    Managing Network Adapter Associations

    Network Director enables you to configure and view the connectivity or association between a host network adapter and the corresponding physical network adapter on the physical switch. If LLDP is enabled on the physical switch and the virtual switch, Network Director automatically discovers and displays the host network adapter to physical network adapter connection. However, if LLDP is not enabled, you must manually configure these connections by importing the connection details in to Network Director.

    You can automate orchestration by using Network Director only if the host to physical switch connectivity is established. Using the Manage Physical Switch Association table, you can view the connectivity between a host network adapter and a physical switch port. You can also view the virtual switch that is bound to the given host network adapter. If any of the host network adapters is not connected to a corresponding the physical switch port, then follow the steps mentioned in Configure Network Adapter Associations to manually configure network adapter associations.

    After you make any change to the network adapter association, Network Director initiates an orchestration job, if orchestration is enabled for the given virtual network.

    Note: Manual NIC associations are used for orchestration purpose only. They will not be visible in the Datacenter Connectivity page.

    You can do the following tasks to manage network adapter associations:

    Manage Network Adapter Associations

    To view and manage the host associations:

    1. Select the virtual network or the host for which you want to view and manage the associations from the View pane and click Connectivity > Manage NIC Associations from the Tasks pane.

      The Manage NIC Associations page opens. Table 1 describes the fields in this page.

      Table 1: Manage NIC Associations page Field Descriptions

      Field

      Description

      Network Adapter Name

      Network adapter of the host to which the virtual switch is connected.

      MAC Address

      MAC address of the host.

      Physical Switch

      IP address or the name of the physical switch to which the virtual switch is connected.

      Physical Switch Port

      Number of the physical switch port to which the virtual switch is connected.

      Discovered Through

      Displays how the association was discovered:

      • LLDP—Indicates that the association was automatically discovered by Network Director, using LLDP.
      • Manual—Indicates that the association was manually configured, using the Import Associations feature. For detailed steps for importing network adapter associations, see Configure Network Adapter Associations.
      • Blank—Indicates that the association was not discovered or was deleted.

      Virtual Switch

      Name assigned to the virtual switch.

      If it is a standalone virtual switch, then the hostname on which the virtual switch resides is also displayed.

    Configure Network Adapter Associations

    Network Director does not automatically discover or display virtual network adapter to physical network adapter associations if LLDP is not enabled on the physical switch and the virtual switch. In this scenario, you can identify the connection details outside of Network Director by doing one of the following:

    • Use the Edit Association window from the Manage Network Adapter Associations page to edit individual associations.
    • Use the Import Network Adapter Associations page to import one or more associations into Network Director to establish these associations manually.

    To manually configure individual network associations:

    1. Select Cloud Infrastructure in the View pane.
    2. To edit individual associations, from the Manage Network Associations page, select a row and click Edit Association.
    3. in the Edit Associations window, select the hostname of the physical switch and the switch port to which you want the selected virtual network adapter to be connected to.
    4. Click Update to save the details and update the Manage Network Adapter Associations table.

    To manually configure multiple network associations:

    1. Select Cloud Infrastructure in the View pane.
    2. In the Manage Network Associations page, click Import Network Adapter Associations. The Import Network Adapter Associations page opens.
    3. Click Browse and select the CSV file in which you have specified the network adapter associations that you want to import.

      You can download a sample CSV file by clicking Download Sample CSV.

    Network Director imports the associations after checking the connectivity and changes the status of the successful associations to Manual in the Manage Network Adapter Associations page.

    Set Up the Devices for LLDP-Based Automatic Link Discovery

    Network Director enables you to configure and view the connectivity or association between a host network adapter and the corresponding physical network adapter on the physical switch. If LLDP is enabled on the physical switch and the virtual switch, Network Director automatically discovers and displays connectivity between the host network adapter and the physical network adapter and enables the system to perform orchestrations. However, for devices that are directly connected to the ESXi server in your vCenter based data center network, you must perform the following additional steps to enable this autodiscovery:

    To set up automatic link discovery and orchestration for devices that are directly connected to the vCenter based data center network:

    1. Log in to the switch, that is directly connected to the ESXi server in your vCenter based data center network, by using the CLI.
    2. Configure the port ID type, length, and value (TLV) by running the following command:
      [edit]
      user@switch# set protocols lldp port-id-subtype interface-name
    3. Only for QFabric Systems, Virtual Chassis, and Virtual Chassis Fabrics that are connected to the vCenter based data center network, set the LLDP management address by running the following command in the configuration mode:
      [edit]
      user@switch# set protocols lldp management-address IP-address

      IP-address is the management address of the QFabric system, Virtual Chassis, or the Virtual Chassis Fabric system .

    4. Commit your changes.

      The physical device that is directly connected to the ESXi server starts advertising their respective management address through LLDP.

    5. Resynchronize the virtual network from Network Director. For more information about resynchronizing virtual networks, see Managing Cloud Infrastructure.

      Network Director uses the information advertised by the physical device for autodiscovery of links between the physical device and the hosts.

    Export Network Adapter Associations

    You can export network associations to Microsoft Excel and make modifications outside Network Director and later import the modified associations into Network Director. Exporting network adapter associations are also beneficial if you were to reinstall Network Director. In case of a reinstallation, you would have to configure all the manual associations after reinstalling Network Director. To save this trouble, you can export the network adapter associations before uninstalling Network Director and import the associations once Network Director is reinstalled.

    To export network adapter associations:

    1. Select the virtual network or the host for which you want to view and manage the associations from the View pane and click Connectivity > Manage Network Adapter Associations from the Tasks pane.
    2. Click Export Associations.

      Network Director exports the network adapter associations. Save the file to a location of your choice. Modify the file if required, and import the associations back into Network Director. For detailed steps for importing network adapter associations, see Configure Network Adapter Associations.

    Delete Network Adapter Associations

    You can delete the network adapter associations that you no longer want to use, from the Manage Network Adapter Associations page.

    Note: You cannot delete LLDP associations that are automatically created by Network Director.

    To delete a network adapter association:

    1. Select the row corresponding to the network adapter association that you want to delete and click Delete Association.
    2. Confirm the deletion.

      Network Director deletes the selected association.
