QoS Prioritization for VoIP using DiffServ
Hello,
I am trying to understand and configure QoS prioritization for VoIP using DiffServ (46).
I find this configuration very counter-intuitive, but we have about 50 of them, so I have to figu...
I apologized for the late response. :( I forwarded your recent post to the higher tier of NETGEAR Support and just got a feedback today.
As per the higher tier of NETGEAR Support, based from the attachment, the configuration looks fine on AF31 and EF46 for DSCP.

Hi RI-IT,
Welcome to the community! :)
I inquired your post to the higher tier of NETGEAR Support and just got a feedback today. As per the higher tier of NETGEAR Support, QoS on VOIP Traffic is an expedited forwarding, specific VOIP configuration. NETGEAR switch/es can prioritize this traffic using the DSCP traffic queue manager. When the higher tier of NETGEAR Support configured it, it was set to 5 – 6 level priority. Never had set it to 7 which had been a preferred rule and it seems to be fine.
The class_voip configuration is only necessary if the phone does not attach to the packet 101110 bit value. Then, you need to go in and manually setup a class for the QoS purpose. Now if the phone does add this bit value, then simple DSCP priority should already be EF as soon as DSCP is enabled. Following the guide here, it seems it needs to be updated for the new GUI as well as some of the configurations are seemingly incorrect and not correctly appropriated.
