I have never seen QOS applied to a vlan interfaces but the thought crossed my mind why or why not use QOS on a vlan interface?
I looked at the commands under a vlan interface and there is not any QOS commands available so I suppose there is no way to configure QOS.
I understand that basically a vlan interface is a virtual interface and not a physical one.
Is that why? But aren't the buffers queues for the interfaces kind of virtual also?
Maybe the question is contrast and compare real interfaces vs virtual interfaces?
