Ensure that the ESXi host has the correct date and time set. See ESXi Host Time Configuration Issue for more information.

Applying Licenses

The order in which you apply your Cisco Modeling Labs license is important.

  • You must apply your base license (R-PID) first and then apply any remaining expansion license(s) (L-PID).

  • Applying an expansion license before a base license will result in an error.

To resolve this issue, remove all licenses and then re-apply them starting with your base license (R-PID).

    Step 1   Click File > Preferences > Node Subtypes.
    Step 2   Click the Fetch from Server button. The Confirm dialog box is displayed.
    Step 3   Click OK to update the list of node subtypes.
    Figure 1. Fetch Node Subtypes from Server



    Step 4   Click OK to finish.

    The updated list of node subtypes is available for use in the Topology Palette view.

    Contact your system administrator if a specific node subtype is missing from the list, as the system administrator is responsible for adding new node subtypes to the Cisco Modeling Labs server.

    ESXi Host Time Configuration Issue

    To resolve this issue, ensure that the ESXi host has the correct date and time set as follows:

    • On the ESXi host, select Configuration > Time Configuration.

    • Update the Date & Time field as necessary.
