Hello Natasha,
Pruning increases available bandwidth on a trunk ??
Pruning basically reduces the VTP broadcasts on the trunk.. You cannot remove traffic flowing on a trunk by pruning. You need to use access lists in this case...
use the command : vtp pruning on the global mode.
YOu can also selectively prune the broadcasts on the trunk by the command : switchport trunk allowed vlan x,y,z on the trunk interface.
Cheers

Nathasha,
I would prune your trunks manually on as needed basis per
interface. Unless all your switches in you VTP domain are running images
where the pruning code is stable, and proven
reliable, you could break your network. How do I know this? Because it
happened to me once
although it was a while ago on some catalyst 6509s. I used the global
command "set vtp pruning enable" and 1 of the switches had a bad image in
it. This caused the vlan to break - dhcp and other
network services. Good Luck.
