Mike,
Do a show vtp status on both sw1 and sw2 to make sure what the vtp mode is
on each. If either one is transparent, vlan's defined on one won't be
propagated to the other.
Also, check if pruning is enabled. If pruning is enabled and there aren't
any ports in those vlan's, the vlan's will be pruned from the trunk.
Also, how were the vlan's created? If the command int vlan X was used, the
vlan doesn't automatically get created (or become active) until a port is
assigned to that vlan or you manually create the vlan with the command vlan
X. In such a case, vtp won't propagate the vlan info across the trunk.
HTH, Tim
