Selects the trunk port for which VLANs should be pruned, and enters
interface configuration mode.
Configures the list of VLANs allowed to be pruned from the trunk.
For explanations about using the add, except, none, and remove
keywords, see the command reference for this release.

use a hyphen to designate a range of IDs. Valid IDs are 2 to 1001.
Extended-range VLANs (VLAN IDs 1006 to 4094) cannot be
pruned.
VLANs that are pruning-ineligible receive flooded traffic.
The default list of VLANs allowed to be pruned contains VLANs
2 to 1001.
