Rapid per-VLAN spanning tree capture of a trunk port, configured with native VLAN 5, VLAN 1 is also active over the trunk.
Capture shows that 3 BPDUs are sent out, one for classic STP (Frame 4, for example), one for the native VLAN 5 (not tagged - Frame 5) and one for each other active VLAN (tagged - Frame 3).
The PVST BPDUs contain the VLAN ID at the end of the frame (01 and 05, respectively).
