On MPC10, MPC11, and LC9600 supported platforms, interface statistics are exported as zero when stats are exported for non-local interfaces. 

Example of telemetry packet sent by the router which shows Zero values : 

    interface_stats {
        if_name: "et-1/7/2"
        init_time: 1652749598
        snmp_if_index: 0
        parent_ae_name: ""
        ingress_stats {
          if_pkts: 0                               
          if_octets: 0                             
          if_1sec_pkts: 0
          if_1sec_octets: 0
          if_uc_pkts: 0
          if_mc_pkts: 0
          if_bc_pkts: 0
          if_error: 0
          if_pause_pkts: 0
        }


This misbehavior might cause the links in the Northstar controller to report a high link utilization value.

This issue is fixed in the pr 1666180
