Troubleshooting VTP
The following are some common things to check when troubleshooting
problems with VTP:
■ Make sure you are trunking between the switches. VTP is sent only
over trunk links.
■ Make sure the domain name matches on both switches (name is case
sensitive).
■ If the switch is not updating its database, make sure it is not in transparent
mode.
■ If using passwords, make sure they all match. To remove a password,
use no vtp password.
