Issues Covered – Clause 8 Frame Format Changes New header format proposed Remainder of formats untouched Header, Payload, Trailer, HEC coverage explicitly defined Request for contributions on HEC replacement with CRC32 Change to fairness frame format deferred to WG. Priority Handling Text describing this should be removed from clause 8 Bit ordering Figure 8-1 to be reworked to clarify bit ordering and PHY responsibilities Ringlet Selection Text needed, adhoc to be formed Control TTL Field questions Questions answered, field retained Application dependent frame formats moved to informative annex May 9, 2002 802-17-01-nnnnn, iii_xxxxx_vv

Issues Covered – Clause 8 MAC Address definition subclause To be removed and replaced with reference to 802-2001 802.17 should adopt Ethernet CRC definition May 9, 2002 802-17-01-nnnnn, iii_xxxxx_vv
