efmCuPmePeerLineAtn

Module: EFM-CU-MIB

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

OID (numeric): 1.3.6.1.2.1.167.1.2.3.1.8

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: The current Line Attenuation in dB as perceived by the remote (link partner) PME. The value of 65535 is returned when the PME is Down or Initializing.

This object is irrelevant for the -R PME subtypes. The value of 65535 SHALL be returned in this case.

If a Clause 45 MDIO Interface is present, then this object maps to the 20P/2B link partner Line Attenuation register.

What is efmCuPmePeerLineAtn?

This read-only value (in dB) reports the line attenuation as measured by the remote link-partner PME, returning 65535 when the link is down/initializing or for -R subtype PMEs where it's irrelevant. Comparing local and peer attenuation readings can reveal asymmetric loop conditions on a copper pair.
