Usage Guidelines When you save VTP mode, domain name, and VLAN configurations in the switch startup configuration
file and reboot the switch, the VTP and VLAN configurations are selected by these conditions:
•
•
The vtp file filename cannot be used to load a new database; it renames only the file in which the existing
database is stored.

(Optional) Set the mode for VLAN VTP database. This is the default (only
VTP version 3).
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.
(Optional) Specify that the key generated from the password string is saved
in the VLAN database file. When the hidden keyword is not specified, the
password string is saved in clear text. When the hidden password is entered,
you need to reenter the password to issue a command in the domain. This
keyword is supported only in VTP version 3 .
(Optional) Allow the user to directly configure the password secret key (only
VTP version 3).
Enable VTP pruning on the switch.
Set VTP version to version 1, version 2, or version 3.
Modification
This command was introduced.
If both the VLAN database and the configuration file show the VTP mode as transparent and the
VTP domain names match, the VLAN database is ignored. The VTP and VLAN configurations in
the startup configuration file are used. The VLAN database revision number remains unchanged in
the VLAN database.
If the startup VTP mode is server mode, or the startup VTP mode or domain names do not match the
VLAN database, VTP mode and VLAN configuration for the first 1005 VLANs are selected by
VLAN database information, and VLANs greater than 1005 are configured from the switch
configuration file.
