As I recall, switches will add the VLAN tag on frames entering a VLAN configured port & remove the tag once the frame exits the switch. Assuming VTP is enabled in a LAN topology because all VLAN members do not reside on the same switch, is the VLAN tag added & removed on *each* switch traversed?
Thanks for any clarification provided.

The tags are added and stripped on ingress and egress from access ports.
If a host sends a frame into a VLAN port on switch A, then the frames traverses a trunk port to switch B, then exits to a host from an access port on switch B, the TAG is applied on switch A, then stripped on switch B. THe frame keeps the tag through the trunk.
Good Luck
