【Problem Description】: We have followed the examples on document. But the control-vlan 10 is not adding. It says Vlan 10 is already used. Please find below screen shot for the error we are facing. This is a new switch and we have not used any vlan anywhere. Then how does it say vlan already used. Also find the attached file for switch configuration.

【Problem Analysis】:check the configuration and make a mirror test in lab device .

Same test result in lab .

【Root Cause】: The control VLAN must be not created, and is not used by other features. In addition, no interface is added to the control VLAN.

【Solution Description】:

Please remove vlan 10  from these interfaces .
