Below is my current VoIP config on a Cisco 3750 with data vlan1 and voip vlan100
int gig1/0/1
description NEC VOIP
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk allowed vlan 1,100

Now I want to move my data subnet from vlan1 to vlan20. So I have to add native vlan20 in my config.Correct?
int gig1/0/1
description NEC VOIP
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk native vlan 20
switchport trunk allowed vlan 1,100,20
