[Symptom]
Changing to VTP transparent causes stop to send the packets.

[Workaround/Solution]
Changing vtp mode to server again and "shut down/ no shutdown"
on interface FE0/1:C3512XL-C.It need to be changed the STP topology.

[Impact]
All the software features running on the switch may stop to send the
packets. They do not change the vtp mode.
