Standard:IEEE Std 802.1Qcp-2018Clause:48
Clause title:YANG Data Model
Rationale for revision
Counters addConfirmationsTransmitted and addConfirmationsReceived from clause 12.19.4.1.3.3 in IEEE Std 802.1Q-2018 are missing in YANG module ieee802-dot1q-tpmr in IEEE Std 802.1Qcp-2018. It appears they should be there.
Proposed text
a) In ieee802-dot1q-tpmr, add the following leaf after leaf add-notificatons-tx: leaf add-confirmations-tx { type yang:counter64; config false; description "The number of add confirms transmitted (23.6.17) by the Port's Transmit Process as a consequence of txAddConfirm being set. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of 'discontinuity-time'."; reference "12.19.4.1.3.3 of IEEE Std 802.1Q-2018"; } b) In ieee802-dot1q-tpmr, add the following leaf after leaf add-notificatons-rx: leaf add-confirmations-rx { type yang:counter64; config false; description "The number of add confirms received (23.6.12) by the Port's Receive Process. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of 'discontinuity-time'."; reference "12.19.4.1.3.3 of IEEE Std 802.1Q-2018"; } c) Update all related figures, tables, and text in clause 48 accordingly.
Impact on existing networks
Conformant TPMR implementations provide both counters (cmp. IEEE Std 802.1Q-2018, 5.15, item e)). The counters are not yet visible via YANG, but they are visible via MIB (cmp. IEEE Std 802.1Q-2018, Table 17-17).
