When enabling VTP pruning, where does it need to be configured?

VTP pruning needs to be configured only on the VTP server. The clients will receive the update and turn on VTP pruning automatically. If VTP pruning is turned on at the VTP client, the setting will be ignored since the client is a slave to the master server. If the VTP pruning is configured on a VTP transparent, the configuration will be ignored since VTP transparent switches do not participate in VTP with other switches.
