VTP pruning removes information about each pruning-eligible VLAN from VTP updates if there
are no stations belonging to that VLAN.
If you enable pruning on the VTP server, it is enabled for the entire management domain for VLAN
IDs 1 to 1005.
Only VLANs in the pruning-eligible list can be pruned.
Pruning is supported with VTP Version 1 and Version 2.
Toggling the Version 2 (v2) mode state modifies parameters of certain default VLANs.
Each VTP switch automatically detects the capabilities of all the other VTP devices. To use
Version 2, all VTP switches in the network must support Version 2; otherwise, you must configure
them to operate in VTP Version 1 mode.
If all switches in a domain are VTP Version 2-capable, you need only to configure Version 2 on one
switch; the version number is then propagated to the other Version-2 capable switches in the VTP
domain.
If you are using VTP in a Token Ring environment, VTP Version 2 must be enabled.
If you are configuring a Token Ring bridge relay function (TrBRF) or Token Ring concentrator relay
function (TrCRF) VLAN media type, you must use Version 2.
If you are configuring a Token Ring or Token Ring-NET VLAN media type, you must use Version 1.
In VTP version 3, all database VTP information is propagated across the VTP domain, not only
VLAN database information.
Two VTP version 3 regions can only communicate over a VTP version 1 or VTP version 2 region in
transparent mode.
