Thanks. The first one is already in our config; we were thinking about configuring "no spanning-tree vlan 1-4095" in a maintenance window. I hope that won't break our single MST instance but does kill off all PVST+ stuff. Still, I wonder whether it will have the desired effect. Our intention is completely ignoring or dropping occasional inbound PVST+ frames on the Cat6k. They might be sourced from equipment out of our control...
