unable to add VLANS
can forward VLAN information to other swithces in the same VTP domain
Client
A switch running in VTP Transparent mode will not participate in VLAN synchronization. With VTP version 2, it will forward VLAN traffic out its trunk interfaces.

In very simple language. Cisco switches can be configured in VTP Server, transparent or client mode. VTP server is the default mode in most everyday switches. The switch must be in server mode in order to create,add, delete VLAN's in the same domain. If I am using more than one switch, the one with the lowest MAC address is the one I would use to be my STP. The other switch would be in CLIENT mode (my preference).
VTP transparent mode allows a switch to forward VTP advertisements but does not participate in the VTP domain. This mode is useful when you want to maintain VLAN information locally without affecting the rest of the VTP domain.
The VTP domain cannot be modified.

Switches may not be sharing VLAN Trunking Protocol (VTP) messages for several reasons. They might be in different VTP domains, preventing them from exchanging information. Additionally, if one or more switches are set to "client" mode while others are in "transparent" mode, the clients will not share VTP messages with the transparent switches. Lastly, issues such as trunk link misconfigurations or mismatched VTP versions can also hinder message sharing.
