Greetings, I have a question regarding LAN QOS.

If I want to mark all packets on an access port of a 3550 with a COS of 5,
would the config below work? In some references regarding LAN QOS that I
have read tells me that the COS field only shows up in an ISL or Dot1Q
header. If that is true, and you simply have a PC connected to the access
port, must you configure the port as a trunk? Please help me understand how
this works.

Thanks,
Christian
