Usage Guidelines

Before you use this command, you must enable VTP on the switch by using the feature vtp command.

The default configuration file is stored in the VTP database, vlan.dat, in NVRAM. VTP configuration information is also stored in the startup configuration file.


Note Do not delete the vlan.dat file.


When a switch in a VTP domain reloads, the switch updates the VTP domain and VLAN configuration information from the information contained in the VTP database file (vlan.dat) or the startup configuration file. Depending on the VTP mode configured for the switch, the information is updated as follows:

Examples

This example shows how to store the VTP configuration to a file named myvtp.txt in the local writable storage file system, bootflash:

switch(config)# vtp file bootflash:///myvtp.txt
switch(config)#
