Cisco Systems 3560 Manual Do Utilizador

See the 

. VTP pruning takes effect several seconds after 

you enable it. VTP pruning does not prune traffic from VLANs that are pruning-ineligible. VLAN 1 and 
VLANs 1002 to 1005 are always pruning-ineligible; traffic from these VLANs cannot be pruned. 
Extended-range VLANs (VLAN IDs higher than 1005) are also pruning-ineligible.

VTP pruning is not designed to function in VTP transparent mode. If one or more switches in the 
network are in VTP transparent mode, you should do one of these:

Turn off VTP pruning in the entire network.

Turn off VTP pruning by making all VLANs on the trunk of the switch upstream to the VTP 
transparent switch pruning ineligible.

To configure VTP pruning on an interface, use the switchport trunk pruning vlan interface 
configuration command (see the 

). VTP 

pruning operates when an interface is trunking. You can set VLAN pruning-eligibility, whether or not 
VTP pruning is enabled for the VTP domain, whether or not any given VLAN exists, and whether or not 
the interface is currently trunking.
