1560.0. "DEFTA addressing, ISO 9314" by 45769::DAVIDSONS () Thu Jan 26 1995 06:22

A customer asks following two questions:

1. Does the DEFTA card support bit significant group addressing mode as
defined in ISO 9314-2 Annex A.2?

2. Which conventional group addresses are reserved by DECnet and other services
used by system software (OSF)?


I assume the answer to first is yes but couldn't find it documented anywhere?
Can someone confirm?

Is files::registry/ethernet-registry-public.ps the best document to answer
second question?

Thanks,
	Stuart.

1) Yes, the DEFTA supports multicast (group) addressing.

2) This is a strange question.  None are "reserved" per se though many
   DNA specs define multicasts.  There is no limit on which group addresses
   may be set and so any adapter has to be able to deal with any group address.
   Note only that but the adapter must also be able to support setting of
   additional individual addresses.
1560.3does he mean functional addresses ?edwin.mko.dec.com::GULICKThose dirty rings !!Thu Jan 26 1995 11:466
I don't have a copy of the ISO document but BIT SIGNIFCANT group addresses are a
code word for the brain-dead 802.5/IBM functional addresses used on Token Ring
LANs not FDDI (to the best of my knowledge). The DEFTA would be able to support
them if they were.
