Issues covered highlights

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


Issues covered highlights1

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


Issues covered highlights2

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


Main issues list

Main Issues List

  • Topology database update in passthrough mode scenarios
