Hi
VTP Pruning requires a VTP domain on all switches ie VTP Server/Client
running. When VTP Transparent is used VTP pruning is not supported so
you need to manually allow specific VLAN's on trunk ports when you want
to restrict things.
At least that's the way I remember it :)

Duane

Subject: trunk allowed vs pruning
Hi all,
I keep confusing myself and need some clarification.
What's the relationship between "vtp pruning" and "switchport trunk
allowed"?
In one of the workbook labs, one of the tasks states:
1. although it does not have it locally assigned ensure that SW1
receives traffic for vlan 8 over Fast0/13 2. traffic for vlan 8 should
not be received over any of the other trunk links.
(The two switches are trunked together on Fast0/13-15 using dot1q.)
So my thinking is to do "switchport trunk allowed vlan 8" on fast0/13
and to not allow it on 14 & 15.
But the solution says the answer is "switchport trunk pruning vlan
2-7,9-1001".
How does this solution solve either of the two tasks?
Please advise,
-tim
