Pris, In our 6509's we used to make the native vlan and the data vlan the same and it was something other than 1...if a blade fails and we put in a new one , it defaults to vlan 1 for all ports. If the blade has trunk ports in it, they get set to native vlan 1. The other end is set for something else, this resulted in vlan mismatch in the vtp domain, and in a lot of instances we suffered stp recalcs that took buildings down for periods of time...we subsequently have returned to making native vlan 1 on all trunks and have not had any issues since..
