Setting device VLAN database password to WATER.
Switch#

Switch(config)# vtp password
password_string [hidden | secret]
Sets a password, which can be from 8 to
64 characters long, for the VTP domain.
In VTP version 3 the keywords hidden and secret
are available.
• If the hidden keyword is used, the secret key
generated from the password string is saved
in the const_nvram:vlan.dat file. If a takeover
command is issued, that password must be
reentered.
• If the secret keyword is used, the password
secret key can be directly configured. The
secret password must contain 32
hexadecimal characters.
Switch(config)# no vtp password
