Hi guys,

Just want to make sure my understanding about layer 2 qos.

Layer 2 packet that we should call it frame, don't have tos bit in their frame. So Qos that Ieee called it 802.1p qos bit only can be carried by isl and dot1.q frame, is that correct?

So, when I have a switchport connected to cisco ip phone that in default will forwarding frame with cos of 5. The switch port have to be a trunk, cause if not, isl or dot1q cannot carried the tos. Is that right?

Can anybody correct me if I'm wrong.

Thanks a lot guys
