Chapter 8 Configuring VLANs
Using VTP
Disabling VTP Version 2
Beginning in privileged EXEC mode, follow these steps to disable VTP version 2:
Enabling VTP Pruning
Pruning increases available bandwidth by restricting flooded traffic to those trunk
links that the traffic must use to access the destination devices. You enable VTP
pruning on a switch in VTP server mode.
Pruning is supported with VTP version 1 and version 2. If you enable pruning on
the VTP server, it is enabled for the entire VTP domain.
Only VLANs included in the pruning-eligible list can be pruned. By default,
VLANs 2 through 1001 are pruning eligible on Catalyst 2900 XL and
Catalyst 3500 XL trunk ports. For information, see the “Changing the
Pruning-Eligible List” section on page 8-42.
