Tagging @CCWTech as we are discussing this. This sums up the VLAN for VoIP issues..
I love it! I'm tempted to send this to him!! What an idiot.
While this is totally true from the protocol point of view, the entire VLAN getting priority over all other traffic not in the VLAN is better than no QoS at all.
@scottalanmiller likes to neglect to mention this in his zeal.
802.1Q does provide QoS. Yes, it prioritizes everything, but any network with VLANs configured properly will still see a benefit to the traffic within the prioritized VLAN.
Under normal circumstances, the amount of non RTP traffic in the VLAN is negligible and honestly not relevant to any discussion outside of theoretical mental exercises on 100% best possible prioritizaiton discussions.
Now that said, I never recommend using a VLAN for voice in the first place, because that is not the purpose of a VLAN. I always recommend setting up proper DSP tag based QoS as a primary resolution.
I was arguing with another tech... He made the statement that he sets up VLANs for all VOIP clients for better performance.
Even before seeing Scott's video on the subject. I told the tech he was up in the night and that setting up a VLAN isn't done for performance... I was called 'unprofessional' and a 'goof' for not doing VLANs for all my clients VOIP systems... After seeing Scott's video, I could see that everything I was saying to the guy was true. The tech responded by posting a link to a CISCO article covering very large enterprise environments. He's dealing with offices of 20 computers or less and can't understand why SMB would be any different than a significantly large enterprise network.
He's adding equipment and services at a premium price. Ripping off his clients. Very unethical.
