Requested revision
| Standard: | IEEE Std 802.1Qcz-2023 | Clause: | 48.5.13 |
| Clause title: | Schema for the ieee802-dot1q-ats YANG module | ||
Rationale for revision
IEEE Std 802.1Q-2022 amendment of 802.1Qcz added YANG for ATS. It defines schedulers and scheduler-groups under stream-filter-instance-table list. It will create each schedulers and scheduler-groups per entry of stream-filter-instance-table. However, 802.1Q-2022 states that - "There is one Scheduler Instance Table per Bridge component." in 12.31.5 The Scheduler Instance Table - "There is one Scheduler Group Instance Table per Bridge component." In 12.31.6 The Scheduler Group Instance Table Based on above clause, I believe YANG tree doesn't match to standard.
Proposed text
Based on 802.1Q-2022 clause 12.31.5 and 12.31.6, both schedulers and scheduler-groups should move out from
Stream-filter-instance-table to same level of stream-filters and stream-gates under dot1q:component as below tree definition.
For this, 48.6.13 The ieee802-dot1q-ats YANG module (ieee802-dot1q-ats.yang) needs updates.

----Impact on existing networks
Existing YANG configuration needs to be updated.
