The fabric statistics counters are not displayed in the output of "show snmp mib walk ascii jnxFabricMib". Not updating Fabric Counts.
PFE Telemetry streaming for AFT/ULC cards to RE is broken causing jnxFabricMib not getting updated.
The limitation has been rectified/Fixed from the Junos Version 23.4R2-S6.
