Customer configures the telemetry GRPC tunnel on the MX304 for telemetry collection. However, the server team noticed that on server side there has no streamed data for the sub-interfaces queue, the ipv6 data(sensor /interfaces/interface) and the OAM(sensor: /state/protocols/oam/ethernet/connectivity-fault-management/< >).

MX304 telemetry data parameters missing sub-interface queue data, ipv6 and OAM data in intervals

This problem can be seen in higher release that switches to use aggregation telemetry data feature. In such releases, the streamed output packets sent from PFE is getting dropped at na-grpcd(PR1812666).

Customer can upgrade to 23.2R2-Sx release, which has reverted back to the legacy data path.

Customer can also upgrade to PR1812666 fixed release with the aggragation telemetry data feature.
