I have new vlans and the same thing. Here's the output as requested.
I have a 2960X trunked to a Nexus 9K.
On the 2960 the trunk port amber and is:
switchport trunk allowed vlan 170,949
switchport trunk native vlan 949
switchport mode trunk
On the 9K the trunk port is green and is:
switchport
switchport mode trunk
switchport trunk native vlan 949
switchport trunk allowed vlan 170,949
no shutdown
On the 2960:
