"Any untagged frames will get tagged..."

Mmmm...sounds kinda contradictory doesn't it? Actually, frames assigned to
the native VLAN of the trunk are sent untagged across the trunk, period. But
one might ask, "how would the switches on each end know when there's a
native VLAN mismatch?" The answer for Cisco switches is through CDP. If CDP
is disabled or not available, then they wouldn't know and you can pretty
much bridge the two VLANs together and maybe not know it...

Any untagged frames will get tagged to the native vlan and travel the native
vlan.
