jf_report_top_prot_013/13/ 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

jf_report_top_prot_013/13/ 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

jf_report_top_prot_013/13/ 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
