[c-nsp] 6509 VSS and Disappearing Vlans

[Bradley Williamson]

Hello all,

We had a case last week where two vlans were deleted from the vlan database on our 6509 VSS.

I was the only one logged in at the time and I was configuring a port-channel interface when the problem occurred. I was not doing anything with Vlans.

The VTP mode on the switch is server and it is not layer2 connected to any other switch so there was no VTP overwrite of the Vlan database.

Have any of you seen anything like this before?

Thanks,

Brad
