802.1Q Native VLAN on Cisco IOS Switch

Hello,

Maybe it’s the phrasing throwing me off, but I’m not clear what’s being said in the first
paragraph:

“The IEEE 802.1Q trunking protocol describes something called the “native VLAN”. All traffic sent and received on an interface that is configured for 802.1Q won’t have a tag on its Ethernet frame. When you look at it in Wireshark, it will look the same just like any normal Ethernet frame.”

Specifically, this part:

“All traffic sent and received on an interface that is configured for 802.1Q won’t have a tag on its Ethernet frame.”

The way it’s worded, it appears to say that NO traffic going across a trunk port will be tagged. We all know that’s not the case (and I know that wasn’t the intent of that sentence). Trunks are designed to carry tagged traffic. That’s why they exist. Can you explain in a different way what was meant by that statement?
