2. Normative references Insert the following references in alphanumeric order: IEEE Std 802.1Qbv™, IEEE Standard for Local and metropolitan area networks—Bridges and Bridged Networks—Amendment 25: Enhancements for Scheduled Traffic. IEEE Std 802.1Qci™, IEEE Standard for Local and metropolitan area networks—Bridges and Bridged Networks—Amendment 28: Per-Stream Filtering and Policing. NOTE—IEEE Std 802.1Qbv and IEEE Std 802.1Qci are both amendments to IEEE Std 802.1Q-2014, as is this standard. This NOTE and the references to IEEE Std 802.1Qbv and IEEE P802.1Qci will be removed when this standard is incorporated into the IEEE 802.1Q base standard in the next revision.
5. Conformance 5.4 VLAN Bridge component requirements 5.4.1 VLAN Bridge component options Insert new subclause 5.4.1.9 as shown, renumbering as necessary: 5.4.1.9 Cyclic queuing and forwarding (CQF) requirements A VLAN Bridge component implementation that conforms to the provisions of this standard for CQF (see Annex T) shall a) Support the enhancements for scheduled traffic as specified in 8.6.8.4. b) Support the state machines for scheduled traffic as specified in 8.6.9. c) Support the state machines for stream gate control as specified in 8.6.10. d) Support the management entities for scheduled traffic as specified in 12.29. e) Support the requirements for per-stream filtering and policing (PSFP) as stated in 5.4.1.8. f) Support the management entities for PSFP as specified in 12.31. NOTE—The enhancements for scheduled traffic are defined in IEEE Std 802.1Qbv, and PSFP is defined in IEEE Std 802.1Qci, both of which are amendments to IEEE Std 802.1Q-2014, as is this standard. This NOTE will be removed when this standard is incorporated into the IEEE 802.1Q base standard in the next revision. 5.13 MAC Bridge component requirements 5.13.1 MAC Bridge component options Insert new subclause 5.13.1.2 as shown, renumbering as necessary:
5.13.1.2 Cyclic queuing and forwarding requirements A MAC Bridge component implementation that conforms to the provisions of this standard for CQF (see Annex T) shall a) Support the enhancements for scheduled traffic as specified in 8.6.8.4. b) Support the state machines for scheduled traffic as specified in 8.6.9. c) Support the state machines for stream gate control as specified in 8.6.10. d) Support the management entities for scheduled traffic as specified in 12.29. e) Support the requirements for PSFP as stated in 5.13.1.1. f) Support the management entities for PSFP as specified in 12.31. Insert the following new subclause at the end of Clause 5, renumbering as necessary: 5.28 End station requirements — Cyclic queuing and forwarding An end station implementation that conforms to the provisions of this standard for CQF (see Annex T) shall a) Support the enhancements for scheduled traffic as specified in 8.6.8.4. b) Support the state machines for scheduled traffic as specified in 8.6.9. c) Support the state machines for stream gate control as specified in 8.6.10.
