  1. Topology/Protection CommentResolution Summary Jason Fan, Section Editor (jason@luminous.com) Jim Kao, Technical Editor (jkao@cisco.com)

  2. Clause 10 and Annex K • 302 comments • 79 technical binding • 70 technical non-binding • 153 editorial • Adhoc group resolution (technicals) • 129 accepted, accepted/mod, accepted/dup • 23 superceded • 0 rejected • 4 punted to WG (4 technical binding) • 3 withdrawn • Editorial license requested

  3. Issues Covered: Highlights • Revised protection state machine added • Protection behavior with FS and SF on span corrected • Protection rules to be reorganized • Topology database update state machine added • Topology validation state machine added • Additional specification of topology validation checks • Instability defect timer set to 10 * slow TP frame periodic timer • Uniform edge status determination and reporting for steering and wrapping • State machine handling for passthrough • Specification of criteria for entry and exit of context containment and other relevant modifications

  4. Issues Covered: Highlights • Wrap/steer preferred modified to wrap/steer configured, defect triggered to higher layers on configuration mismatch • Sequence number check will be per span of the station • TLVs • Rules addded for discarding/updating/triggering TLVs • Vendor-specific TLV modified to organization-specific • TLVs added for station management address and interface index • Station bandwidth TLV made optional with default of 0 • Station name TLV given range of 0 to 127 bytes • TLV timer range given range of 1 to 10 seconds with 1 second resolution and 1 second default

  5. Issues Covered: Highlights • MIB attributes added for some TBDs • Determination of values for some existing MIB attributes to be specified • MAC editors to modify receive state machine to reset link keepalive timer for valid received SCFF • Consistency with Clause 6 on handling of control frames across edge span • PICS and use of saintly words • Annex K • Scenarios to be added on modification of wrapping ring to steering ring and vice versa, passthrough mode, duplicate MAC address checking, and too many stations on ring checking • Existing scenarios to be deleted • List of scenarios to be filled in to be specified

  6. Main Issues List • Topology database update in passthrough mode scenarios • Context containment entrance and exit criteria and mechanisms • Simulation and/or reference implementation • Timer settings and ranges/resolution • TLV update • Scope of new features: secondary MAC address? • PICS • General editorial modifications

  7. Punts • 4 punts to WG • 644 (TB), 760 (TB), 870 (TB), 887 (TB) • Punted from Intro • 151 (TB) • Accepted/modified • Punted from MAC • 316, 317 (TB), 319, 320 (TB), 321 (TB) • All superceded by 887
