Clearing VLANs from Trunk Links
As demonstrated in the preceding sections, all VLANs are configured on a trunk link unless
cleared by an administrator. If you do not want a trunk link to carry VLAN information because
you want to stop broadcasts on a certain VLAN from traversing the trunk link, or because you
want to stop topology change information from being sent across a link where a VLAN is not supported,
use the clear trunk command.
This section shows you how to clear VLANs from trunk links on both the 4000 and IOSbased
series of switches.
