38. VTP is
a Layer 2 messaging protocol. It
carries configuration
information throughout a single
domain. VTP operates in one of
three modes:
1.
Server mode
2.
Client mode
3.
Transparent mode
VTP Servers
can create, modify, or delete
VLANs and other configuration
parameters for the specified
VLAN domain.
A VTP
client can't create, change, or
delete VLANs.
A VTP
transparent mode is used when a
switch is not required to
participate in VTP, but only
pass the information to other
switches. Transparent switches
don't work either as Server or
clients.
Configurations made to a single
switch, called VTP server, are
propagated across the switch
fabric under a single domain
control. Other switches,
configured as VTP clients, learn
the configuration information
from the server.
