10G Managed Switch with gPTP 802.1AS Support
Hi, we are looking for managed ethernet switch with the following parameters:
- At least 4x 10G ports (can be RJ45 or SFP+)
- 802.1AS gPTP (P2P) profile- with focus on not performing BMCA (lack of announce messages)
(https://avnu.org/wp-content/uploads/2014/05/Auto-Ethernet-AVB-Func-Interop-Spec_v1.6.pdf)
Could you please suggest us a possible solution?
Thanks,
Yossi

- Hello,
Any M4250 or M4350 switch will do that for you:
www.netgear.com/m4250
www.netgear.com/m4350
Please look at M4250-26G4XF-PoE+ (GSM4230PX) or M4350-24G4XF (GSM4238)Hello,
Thanks for your feedback!
looking on the datasheets on website, I have seen that it support 802.1AS, but it does not give more details on the profile, could you please approve that it is not performing BMCA (lack of announce messages) ?
can you refer us to the user manual/any resource that related to the supported gPTP profile and possible configuration?
Thanks!
The documentation for M4250 is for instance here: https://www.netgear.com/support/product/m4250/#docs
The user manual (IT configuration of 802.1AS) is there https://www.downloads.netgear.com/files/GDC/M4250/M4250_UM_EN.pdf
Although it's way simpler to enable AVB on the Default VLAN 1 profile in the AV User Interface (one click).
Sorry it I misread your message previously, I don't think we comply with your requirements (lack of announce message, no BMCA). Like PTP, gPTP 802.1AS needs BMCA to learn who is the GM (or being elected itself) - I think we follow the standard with a BMCA for 802.1AS.
