vtp (global configuration)
vtp (global configuration)
Use the vtp global configuration command to set or modify the VLAN Trunking Protocol (VTP)
configuration characteristics. Use the no form of this command to remove the settings or to return to the
default settings.
vtp {domain domain-name | file filename | interface name [only] | mode {client | server |
transparent} | password password | pruning | version number}
no vtp {file | interface | mode | password | pruning | version}
Syntax Description domain domain-name Specify the VTP domain name, an ASCII string from 1 to 32 characters that
identifies the VTP administrative domain for the switch. The domain name
is case sensitive.
file filename Specify the Cisco IOS file system file where the VTP VLAN configuration
is stored.
interface name Specify the name of the interface providing the VTP ID updated for this
device.
only (Optional) Use only the IP address of this interface as the VTP IP updater.
mode Specify the VTP device mode as client, server, or transparent.
client Place the switch in VTP client mode. A switch in VTP client mode is enabled
for VTP, and can send advertisements, but does not have enough nonvolatile
storage to store VLAN configurations. You cannot configure VLANs on the
switch. When a VTP client starts up, it does not send VTP advertisements
until it receives advertisements to initialize its VLAN database.
server Place the switch in VTP server mode. A switch in VTP server mode is
enabled for VTP and sends advertisements. You can configure VLANs on
the switch. The switch can recover all the VLAN information in the current
VTP database from nonvolatile storage after reboot.
transparent Place the switch in VTP transparent mode. A switch in VTP transparent
mode is disabled for VTP, does not send advertisements or learn from
advertisements sent by other devices, and cannot affect VLAN
configurations on other devices in the network. The switch receives VTP
advertisements and forwards them on all trunk ports except the one on which
the advertisement was received.
When VTP mode is transparent, the mode and domain name are saved in the
switch running configuration file, and you can save them in the switch
startup configuration file by entering the copy running-config startup
config privileged EXEC command.
password password Set the administrative domain password for the generation of the 16-byte
secret value used in MD5 digest calculation to be sent in VTP advertisements
and to validate received VTP advertisements. The password can be an ASCII
string from 1 to 32 characters. The password is case sensitive.
pruning Enable VTP pruning on the switch.
version number Set VTP version to Version 1 or Version 2.
