Fill words are what it sends when there's no data to send.

>dont understand this parameter
You haven't set a parameter, you need a 1,2, or 3 at the end of that command.

portcfgqos configures QoS on a trunk, but you've spelt it wrong.

Speed is the speed, 2,4,8 gig etc. Fill word is just waffle because if it didn't send anything the sender/receiver would lose clock syncronisation and the fibre would go down in temperature because the laser would be off during that period.
