task 1.7 - missing some commands in the SG?

wp-

I had the following configured:

global:

mls qos

 

int fa0/7-8:

switchport priority extend cos 0

switchport access vlan 17
switchport voice vlan 7
mls qos trust device cisco-phone (a cisco phone is mentioned in the task?)

I did the same , so by this I am trusting only the cisco-phone CoS

switchport priority extend cos 0

this command is on by default, you use it only to put a value other than 0.
