VTP - Client can't modify VLANs

When configuring VTP, a switch that is configured as a client cannot make any changes to VLANs. This is the case for all versions of VTP.

If an attempt is made to make such a change, the following error message appears:

%VTP VLAN configuration not allowed when device is in CLIENT mode.

Only VTP servers can make changes. In the case of VTPv3, only primary servers can make such changes.
