Re: [EFM] RE: OAM Transport Proposal


A management frame I described is that defined in Clause 22 as a MDIO/MDC
communication.  If the preamble is filtered by the PHY, then there has to be
some way to pass this preamble OAM information to the management entity.  In
802.3, this is done via MDIO/MDC (or management frames).  A management frame
takes over 25 us to be passed across the MDIO/MDC interface.  Unless the
intention is to have the PHY handle all OAM in preamble without management
entity intervention, then the response to the OAM in preamble will be
hampered by the MDIO/MDC interface.
