efmCuPAFInOverflows

Module: EFM-CU-MIB

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

OID (numeric): 1.3.6.1.2.1.167.1.1.3.1.11

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Description: The number of fragments, received across the gamma interface and discarded, which would have caused the frame assembly buffer to overflow. 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 overflow 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 efmCuPAFInOverflows?

This read-only counter counts fragments that arrived on the gamma interface and were discarded specifically because accepting them would have overflowed the frame reassembly buffer. Sustained increases suggest the reassembly buffer is undersized or a peer is misbehaving in a way that floods incoming fragments.
