Question about the spec:
How on earth is this going to work?
I mean, if the link partner is not also using CMLDS, then it won't
reply because of the majorSdoId mismatch.
Yes, as we understand, that is indeed the case. IEEE
1588-2019/16.6.3.1/Note 3 emphasizes this point and 16.6.3.2 specifies
the wire protocol variations for CMLDS. So yeah, the link partner is
expected to run an instance of the service and they would interoperate.
Does the standard require that either ALL the nodes in a network use
CMLDS, or none do at all?
When the time-aware system supports multiple domains, IEEE
802.1as-2020/11.2.17 mandates CMLDS and the COMMON_P2P DM.
Thanks,
