Hi All
Is VTP v1 and transparent mode really required to prevent VTP packets
from leaving certain ports? I've always just set the ports to switchport
mode access since VTP can only run on trunks. Or is this only required
to stop the VTP packets over trunks as well?

Version 1 is the default. I wanted to make sure everyone knows
that
because this is not clear when using the show vtp status command. This
command will show VTP V2 Mode, but next to V2, it will display Disabled
(see
below).

This is not enough. All lab scenarios for training have trunk ports
(either
two trunks or one ether-channel) and therefore VTP packets will be sent
out
and recieved on some ports.
The solution is to set VTP mode to transparent and version 1. (V2 VTP
switch
transparently forwards VTP packets, while V1 doesn't)
