efmCuPAFInLostStarts

Module: EFM-CU-MIB

OID (symbolic): EFM-CU-MIB::efmCuPAFInLostStarts

OID (numeric): 1.3.6.1.2.1.167.1.1.3.1.9

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: The number of missing StartOfPacket indicators expected by the frame assembly function. This read-only counter is inactive when the PAF is unsupported or disabled. Upon disabling the PAF, the counter retains its previous value.

If a Clause 45 MDIO Interface to the PCS is present, then this object maps to the 10P/2B PAF lost start of fragment register.

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 ifCounterDiscontinuityTime, defined in IF-MIB.

What is efmCuPAFInLostStarts?

This read-only counter tracks missing Start-of-Packet indicators that the frame reassembly function expected to see but didn't receive, only incrementing while PAF aggregation is active. It helps distinguish 'packet start lost' failures from other fragmentation errors when troubleshooting a bonded link.
