ps:
Keeping switches in transparent mode can eliminate the chance for duplicate,overlapping VLANs in a large network with many network administrators.
ex:
two administrators might configure VLANs on switches in their respective areas but use the same VLAN identification or VLAN number.
Even though the two VLANs have different meanings and purposes, they could overlap if both administrators advertised them using VTP servers.
