Hi.
You can change STP timers per VLAN only (not per port), via global
configuration commands

SW1(config)#spanning-tree vlan 20 ?
  <1-1005> Spanning tree VLAN id
  forward-time Set a Spanning Tree FORWARD Interval
  hello-time Set a Spanning Tree HELLO Interval
  max-age Set a Spanning Tree MAX AGE Interval
  portfast Allow a change from blocking to forwarding
  priority Set a Spanning Tree Priority
  protocol Spanning tree protocol type
  <cr>
