VTP Pruning
The following example shows how to turn on pruning in a 1900 switch. There
is not a whole lot to it. Remember that if you turn VTP pruning on in a VTP
server, you turn it on for the whole domain as well.
Todd1900EN(config)#vtp ?
client VTP client
domain Set VTP domain name
password Set VTP password
pruning VTP pruning
server VTP server
transparent VTP transparent
trap VTP trap
Todd1900EN(config)#vtp pruning ?
disable Disable VTP pruning
enable Enable VTP pruning
Todd1900EN(config)#vtp pruning enable
Todd1900EN(config)#
Notice that you turn VTP pruning on for the whole switch. This will not
send VTP broadcasts down a trunked link if no VLANs configured on this
switch are present down the link.
