efmCuPAFInBadFragments

Module: EFM-CU-MIB

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

OID (numeric): 1.3.6.1.2.1.167.1.1.3.1.7

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: The number of fragments that do not fit into the sequence expected by the frame assembly function and that have been received across the gamma interface and discarded (the frame buffer is flushed to the next valid frame start). 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 bad fragments 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 efmCuPAFInBadFragments?

This read-only counter tracks fragments that arrived out of the sequence expected by the frame reassembly logic and were discarded, forcing the frame buffer to flush and resync to the next valid start. A rising count points to reordering or corruption issues on the bonded copper pairs feeding this PAF.
