Question:

How to configure LTE using Versa Director.


Solution:


Starting 20.X, you can follow the below document 


https://docs.versa-networks.com/Secure_SD-WAN/01_Configuration_from_Director/Common_Configuration/Configure_LTE#


You can configure the LTE interface in the post staging templates (similar to configuring physical ports vni-0/0, vni-0/1 etc.). 


Click LTE icon to configure the LTE interface.


NOTE:  LTE supported interfaces are numbered from vni-0/100 to vni-0/103


Follow these steps to configure LTE using Versa Director:

  1. In the Director view, go to Workflows > Template > Templates and click to create a new LTE interface. This opens the Create Template window.

    Refer to Configuring LTE to configure the Basic tab.

  2. While creating a template using workflows, select the Interfaces tab and click LTE icon in the Device port Configuration section to add LTE(s).
  3. Click the Trash icon in the WAN Interfaces section to delete any additional WAN interface.
  4. Optionally, select the Split Tunnel tab to configure a split tunnel on the WAN link just like a regular ethernet link.
  5. Obtain an LTE link either from an internal modem on the device or from the external dongle.
  6. Ensure that the SIM card is active and working.
  7. Stage the device using URL ZTP or staging script. URL ZTP automatically tries all the available interfaces on the device.
  8. If the script is used to stage the device, use options -w 100 -d for WAN transport.

Versa FlexVNF auto detects the dongle/SIM and retrieves the IP.


Once the LTE link completion, It is recommended to unplug the power cable and plug it back in.



Verifying LTE Configuration

To verify LTE configuration:

  1. Run the show interfaces brief CLI command to view the list of available and configured interfaces.

    admin@versa-flexvnf-cli(config)% run show interfaces brief

  • Ensure that the SIM card is activated and working.
    • Status information must show whether the sim card is connected/enabled.

    • 3GPP information show the operator id.

  • Run the set interfaces vni-0/100 wwan apn <name> to configure the APN to enable the interface when the operator name is not displayed.
