Description (partial)

Symptoms: The vlan.dat file gets deleted after the second reload of the 
router, and the VLAN definition and names are lost (not the interfaces and IP 
addresses). It has been observed that when the vlan.dat is lost, in "sh vtp 
status" the VTP Domain Name is blank (and was properly configured before).
Conditions: This behavior is observed in a Cisco 3270 router that is running 
Cisco IOS Release 12.4(24)T. It is also observed with Cisco 1800 ISR with 
switch modules in Cisco IOS Release 12.4(22)T.
