[c-nsp] 6500 VTP and VLANs disappearing

[Chris Phillips]

Have no idea why it happened.  I assumed it was a bug in the SXF train. 
  It hasn't happened to us again, luckily.

One other characteristic that I remember about it is that it only 
deleted non-extended VLANs.  Was that similar to what happened to you?

Everything has been working fine until this morning we added a couple more vlans. After that we noticed that all but about 80 of the VLANs in the VTP database were missing. Somehow they got erased. No one was in the device since this happened and its configured in trans mode. Any ideas what could have happened? We put the VLANs back in and everything came up fine for now.
