300-415 Question 102
Select 4You are deploying Cisco SD-WAN routers at branch offices and need to configure a vEdge router to connect to the SD-WAN fabric. During the deployment, you notice that the router is unable to establish a secure control connection with the vSmart controller. Which of the following steps should you verify to resolve this issue?
- A
Ensure the router has a valid and activated Certificate Serial Number (CSN).
- B
Check that the router's system IP address matches its configuration in the vManage.
- C
Verify that the transport interfaces are properly configured with reachability to the WAN.
- D
Confirm that the ZTP process has been bypassed by deploying a manual .p12 certificate.
- E
Ensure that the vSmart controller is configured with the same organization name as the router.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
To establish a secure control connection with the vSmart controller, the router must have a valid and activated CSN, a matching system IP address in vManage, properly configured transport interfaces, and the same organization name as the vSmart. These elements are critical for proper authentication, identification, and communication within the SD-WAN fabric. Verifying these items ensures that the router can join the SD-WAN fabric successfully.
- A. Correct.
A valid and activated Certificate Serial Number (CSN) is required for the router to authenticate with the SD-WAN fabric.
- B. Correct.
The system IP address must match the configuration in vManage to ensure proper identification and control connection establishment.
- C. Correct.
Transport interfaces need to be correctly configured and have WAN reachability for the router to communicate with controllers.
- D. Incorrect.
Bypassing the ZTP process is not mandatory and is only needed in specific deployment scenarios. This step is not required to resolve the issue described.
- E. Correct.
The organization name must match across all devices, including vSmart and vEdge, to ensure secure and successful control connections.
