Some vlan stp do not exist

[wfqk]

Hi Vlan 900 exists in the switch4500 and it is native. it shows "Spanning tree instance(s) for vlan 900 does not exist" when using command "show spanning-tree vlan 900. Why is that? 

by command show run | b spanning, we can see "spanning-tree vlan 1-1000 priority 24570"

Thank you
