Some standard even uses vlan 0. Iirc some Qos stuff.
A real world example: interface GigabitEthernet0/21 description uplink cat6509-e switchport trunk native vlan 506 switchport trunk allowed vlan 1,323,506 Has a tagged vlan with ID 1 and an untagged vlan with corrosponds to vlan 506. I have not looked at diff but if the native vlan or untagged ethernet frames are treated as vlan 1 this example vlan 1 and vlan 506 would be mixed.
