config issues in Y1731 in TSDN 3.0.0 M4: NSO has installed with NCS 5.5.2.7 TSDN 3.0.0 M4.Attached payload for configuring y1731 for L2vpn EPVN service and L2vpn p2p service.We have the below listed issues in the configuration of y1731 through CFP. Raised JIRA ticket 1] By Default, It is always configuring SMAN with id icc-based in Ethernet CFM configurations. This should be configurable parameter where this SMAN support varies with different device types.For eg., I have created service between ASR9k and NCS55XX ., After the configuration., I face issues in bringing up the ethernet CFM.The config that got pushed:!ethernet cfm domain EVC level 4 id null service L2NM-L2NM-EVPN-VPWS-SRTE-104 xconnect group L2NM-EVPN-VPWS-SRTE-104 p2p L2NM-EVPN-VPWS-SRTE-104 id icc-based p2p 1  continuity-check interval 1s  mep crosscheck  mep-id 2!Error in device:RP/0/RSP0/CPU0:ASR9006-SDN-91#show ethernet cfm local meps Wed Aug 4 13:03:33.121 UTCDefects (from at least one peer MEP): A - AIS received        I - Wrong interval R - Remote Defect received   V - Wrong level L - Loop (our MAC received)   T - Timed out C - Config (our ID received)  M - Missing (cross-check) X - Cross-connect (wrong MAID) U - Unexpected (cross-check) P - Peer port downDomain EVC (level 4), Service L2NM-L2NM-EVPN-VPWS-SRTE-104  ID Interface (State)    Dir MEPs/Err RD Defects AIS----- ------------------------ &#8212; -------- &#8211; ------- &#8212;  1 Te0/0/0/15.104 (Up)   Up   1/1  Y RX    RP/0/RSP0/CPU0:ASR9006-SDN-91#RP/0/RSP0/CPU0:ASR9006-SDN-91#show ethernet cfm peer meps Wed Aug 4 13:04:41.942 UTCFlags:> - Ok             I - Wrong intervalR - Remote Defect received   V - Wrong levelL - Loop (our MAC received)   T - Timed outC - Config (our ID received)  M - Missing (cross-check)X - Cross-connect (wrong MAID) U - Unexpected (cross-check)<ul>- Multiple errors received  S - Standby</ul>Domain EVC (level 4), Service L2NM-L2NM-EVPN-VPWS-SRTE-104Up MEP on TenGigE0/0/0/15.104 MEP-ID 1================================================================================St  ID MAC Address  Port  Up/Downtime  CcmRcvd SeqErr  RDI Error&#8211; ----- -------------- ------- ----------- --------- ------ ----- -----X   2 0032.17ea.a000 Up   00:04:06     246   0  246  246RP/0/RSP0/CPU0:ASR9006-SDN-91#This got fixed after changing the SMAN id in the device manually as below.,!ethernet cfm domain EVC level 4 id null service L2NM-L2NM-EVPN-VPWS-SRTE-104 xconnect group L2NM-EVPN-VPWS-SRTE-104 p2p L2NM-EVPN-VPWS-SRTE-104 id number 100  continuity-check interval 1s  mep crosscheck  mep-id 2!The are the available attributes for SMAN id under ethernet cfm. Attached snapshot.2] As per the current CFP implementation, SMAN id is getting configured with mep id value. Mep id can be same for the device. But SMAN ID value should be different for each service. Since it is taking the value of mep-id itself for SMAN id also, it is not possible configure same mepid now. We are forced to change the mep-id for every service.3] It is Not able to unconfigure the y1731 configs that got pushed. Please let me know if there is any possibilities to unconfigure only the y1731 config for the particular service .We should have possibility to unconfigure the Y1731 profile association to the services. The below marked config should be configurable and unconfigurable.!interface TenGigE0/0/0/15.104 l2transport description T-SDN Interface encapsulation dot1q 104 no ethernet cfm no mep domain EVC service L2NM-L2NM-EVPN-VPWS-SRTE-104 mep-id 1 no sla operation profile loss target mep-id 2 no sla operation profile delay target mep-id 2 !
 For item 1) and 2): the configuration was push based on configuration governance in git. Please submit your request configuration to configuration governance team for approval.Item3): I applied your payload and able to delete ethernet-service-oam from the service. I don't see any screenshot attached for this issue. Please follow this guide to report the issue.Note: For deleting ethernet-service-oam, it needs to delete ethernet-service-oam from both sides (local and remote) at the same time.Attached email thread Postman collection for delete oam TSN 3.0- Folder- L2VPN-NM-OAM- Delete Y1731 configuration is changed in M6 to address this issue.Wiki and Recording available here -
