Command History
Usage Guidelines If VTP mode is transparent, the mode and domain name are saved in the switch running configuration
file, and you can save the configuration in the switch startup configuration file by using the copy
running-config startup-config privileged EXEC command.
Follow these guidelines when setting VTP mode:
• The no vtp client and no vtp transparent forms of the command return the switch to VTP server
mode.
• The vtp server command is the same as no vtp client or no vtp transparent except that it does not
return an error if the switch is not in client or transparent mode.
• If the receiving switch is in client mode, the client switch changes its configuration to duplicate the
configuration of the server. If you have switches in client mode, make sure to make all VTP or
VLAN configuration changes on a switch in server mode. If the receiving switch is in server mode
or transparent mode, the switch configuration is not changed.
• Switches in transparent mode do not participate in VTP. If you make VTP or VLAN configuration
changes on a switch in transparent mode, the changes are not propagated to other switches in the
network.
• If you make a change to the VTP or VLAN configuration on a switch in server mode, that change is
propagated to all the switches in the same VTP domain.
• The vtp transparent command disables VTP from the domain but does not remove the domain from
the switch.
• The VTP mode must be transparent for you to add extended-range VLANs or for the VTP and the
VLAN configurations to be saved in the running configuration file.
• If extended-range VLANs are configured on the switch and you attempt to set the VTP mode to
server or client, you receive an error message and the configuration is not allowed.
• VTP can be set to either server or client mode only when dynamic VLAN creation is disabled.
