Thank you for asking this question, as well as providing the configuration for reference. Currently, AOS does not have a way to explicitly prevent the native VLAN from traversing a trunk port. It has to be done a little differently. To prevent this traffic on the ADTRAN, perform the following steps to the trunk port configuration:
1.) Allow the desired VLAN to be sent out the trunk port.
2.) Create an unused VLAN as the native VLAN on the trunk (this will prevent the default native VLAN 1 from being allowed out the trunk port).
interface switchport 0/1
switchport mode trunk
switchport trunk native vlan <RANDOM VLAN ID NOT IN USE>
switchport trunk allowed vlan 2
I hope that makes sense, but please do not hesitate to reply to this post with additional information or questions. I will be happy to help in any way I can.
That is the workaround I was using, just wanted to make sure I wasn't missing something.
