A misconfiguration on a switch can cause the configuration updates of the
VTP to fail. In most cases, the problem is that the new VLAN created in the
VTP server switch does not propagate to the VTP client switches, which
creates host connectivity issues.

A common cause for this issue is a VTP version mismatch between the switches
in a VTP domain. VTP version 1 and VTP version 2 are not interoperable on
the network devices in the same VTP domain. A VTP version 2 capable network
device can operate with a network device that runs VTP version 1, provided
that VTP version 2 is disabled on the VTP version 2 capable network device.
VTP version 2 is disabled by default. Every network device in the VTP domain
must use the same VTP version. Verify the VTP version that runs on a switch.
If VTP version 2 is enabled, disable it in order to resolve this issue.

Verify if the switch is configured properly for other VTP parameters:

   -

   Verify that the switches are connected through trunk links, because VTP
   updates are only exchanged over trunk links.
   -

   Verify that the VTP domain name is exactly the same on the appropriate
   switches. The name is case sensitive. The VTP updates are only exchanged
   between switches in the same VTP domain.
   -

   Verify that the VTP password is exactly the same on all the switches in
   the domain. The password is case sensitive. If a password is configured, it
   must be configured on all switches in the domain and the password must be
   the same.

In case of a VTP convergence issue, where a VTP client does not update the
VLAN information, the workaround is to force a VTP convergence by the
creation, then the removal of a dummy VLAN on the VTP server. This
increments the revision number and forces all VTP clients to update their
VLAN database.
