I am an AV Integrator and we are currently planning a project that will be utilizing 3 X465-48P switches. We will be using these as a SummitStack and create a VLAN for Dante Audio, and another VLAN for AES67 audio.
To set up QoS in AV the standard practice is to use DSCP tags and sort out the clocking (PTP), audio, video, and all other traffic priority in that respective order. When using both AES67 and Dante Audio this becomes complicated as the clock tag is 48 in AES67 while the audio tag is 48 in Dante. We have worked with another client who had to place all AES67 traffic on a separate switch in order for the audio to pass so this is not a non-issue. We would like to find a solution that allows for both traffic types to exist on the same switch.
Does anyone have experience with this issue and have any advice for setting this up in the CLI?
For more information:
It seems Netgear AV switches use the multicast address of PTP packets to place them in the highest queue. It then evaluates DSCP packets and sorts them into the appropriate queues. This corrects the issue for the most part as the multicast address is evaluated before DSCP, so any DSCP tags being evaluated will not be of those PTP packets. I cannot tell if I am missing something in the configuration of the Netgear AV switches as most of this is done through profiles that configure these settings automatically. PTP can be transmitted via unicast so I am unsure if their solution covers this in some other way that I have missed while looking through their profile settings. We have used those profiles in the past for other projects containing large amounts of AES67 and Dante and it works, so either missing those packets are not critical to PTP, or there is something I am missing. We would prefer Extreme switches however because of the much larger uplink capability through stacking. Again any help setting this up to work in EXOS would be appreciated.
