               - {slot/port[/sub-port][-slot/port[/sub-port]][,...]} 
- Shows the RSTP port role.
                  {slot/port[/sub-port][-slot/port[/sub-port]][,...]} identifies the slot and port
                  in one of the following formats: a single slot and port (slot/port), a range of
                  slots and ports (slot/port-slot/port), or a series of slots and ports
                  (slot/port,slot/port,slot/port). If your platform supports channelization and the
                  port is channelized, you must also specify the sub-port in the format
                  slot/port/sub-port.
