spanning-tree pvst [edge-port [bpduguard [shutdown-on-violation]] | vlan vlan-range
{cost number | priority value} ]
To disable PVST+ on an interface, use the no spanning-tree pvst [edge-port [bpduguard]
[shutdown-on-violation]] | vlan vlan-range {cost number | priority value} ] command.
Parameters
