[c-nsp] 6500 VTP and VLANs disappearing

[Mike Jones]

I have never come across this, however, if I recall correctly, the Supervisor MSFC should be able to handle at least 3000 IDBs running 12.2 IOS. A physical interface will take 1 IDB, and a logical interface (VLAN or subinterface) will take another IDB. I highly doubt you ran into an IDB limitation on your SUP.Mike J <><

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?

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.
