Is M4300 PTP aware?

[wvrbe]

Hello,

Is the M4300 series compatible with these features:

- support DiffServ (RFC2474) and traffic prioritization according to IEEE802.1p

- support PTP as defined in IEEE1588-2008 with at least E2E Transparent Mode, preferably also Boundary Clock

- Support settings for all necessary PTP parameters to comply with the SMPTE ST2059-2 and AES-R16-2016 profiles

- Support multicast traffic (RFC 1112)

- Support multicast forwarding

- Support IGMPv2 (RFC 2236)

- Support IGMP snooping (RFC 4541)

- Support of min 1024 Multicast groups on a 48 ports switch

- Port to Port latency (10Gb): 5μs

- PTP accuracy for PTP-aware switches: less than 1μs

Based on the datasheet a big part of the blocks are ticked off but not all are clear.

What about the smaller series like the 8 or 12 port?

Greetz,

Wim

Hi @wvrbe 

As this point of time, M4300 series is designed for Pro-AV (IGMP based Video-over-IP) and not for Broadcast (SMPTE based Video-over-IP) as of yet.

In our Pro-AV efforts, to better support AES67 Audio-over-IP variants such as Dante and Q-SYS, we are working on IEEE 1588v2 PTP for our M4300 series, first on 1G models. Lots of our customers and partner AV manufacturers are waiting for this and we will be ready later this year. At this point, our application notes (see our Dante M4300 app note) are using DiffServ to prioritize PTP packets, only. 

It is not a commitment for SMPTE, in particular ST2059-2 nor for ES-R16-2016.

Of course, we will update the Community as soon as we are progressing towards Beta-Testing for PTP, and we will also work with the Broadcast AV manufacturers to evaluate our code against SMPTE.

For now, any SMPTE-related utilization of NETGEAR M4300 series should remain testing and experimentation. For instance, we already saw successful installations using SMPTE 2110 with 3G SDI at our partner L2Tek here. 

As a conclusion, I wouldn't check all your boxes below. I hope this helps!
