what does it mean "no spanning-tree optimize bpdu transmission"? on switch 29xx switch?
What will happen if it is disable?
>> "If the STP is enabled, this feature should be enabled
as I told in my first post leave it exactly as you see
no spanning-tree ...
I think in this way the switch behaves normally by automatically relying BPDUs received on its root port out of all of its ports in forwarding state.(vlan specific)
the command is present in some command references of higher models like c6500.
I agree that is not well documented
Hope to help
