I need your help as by default cisco switches have only 3 modes (pvst+ ,pvst ,MST) and i have more than 200 vlans per switch when i configured the below spanning-tree it shows no spanning-tree on some vlans although i need to be enabled for all of the, same happened on all other switches and when i tried to
#show spanning-tree vlan 198
#Spanning tree instance(s) for vlan 198 does not exist.
spanning-tree mode rapid-pvst
spanning-tree extend system-id
no spanning-tree vlan 198-201,789-790,831,930,932-933
spanning-tree vlan 2-4094 priority 28672
Is there any workaround for this
