Question 246
Correct Answer: D
The issue indicated in the exhibit shows that the state of the control connections is 'tear_down' with an error code of 'CRTREJSER NOERR'. This commonly indicates that there is a problem with the serial number configuration. When troubleshooting such issues, it is essential to ensure that the correct serial number and device model have been configured and provisioned on the PnP portal and the vManage. Sending the serial number to the vBond from the vManage controller typically resolves this issue.
