Issue

SLA is not being established between Versa SD-WAN branch devices when using Cradlepoint as the WAN connectivity.

Environment

  • Versa SD-WAN

  • Cradlepoint modem/router configured as the WAN gateway

Cause

This issue may occur if the Cradlepoint device is not properly configured in passthrough mode or NAT mode , which is required for SLA to be up between Versa branch devices.

Resolution

Versa SD-WAN requires the Cradlepoint device to operate in passthrough mode for SLA to function correctly. It may also work with NAT mode if configured correctly.

To resolve this issue:

  1. Review the attached Cradlepoint golden configuration, which has been verified to work with Versa SD-WAN deployments.

  2. Compare the golden configuration with your current Cradlepoint settings.

  3. Update your Cradlepoint configuration to match the golden configuration if any discrepancies are found.

Note: The golden configuration is designed specifically for passthrough mode operation and should be used as a reference to validate or correct your setup.
