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: 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
