efmCuPmeSnrMgn
Module: EFM-CU-MIB
OID (symbolic): EFM-CU-MIB::efmCuPmeSnrMgn
OID (numeric): 1.3.6.1.2.1.167.1.2.3.1.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The current Signal to Noise Ratio (SNR) margin with respect to the received signal as perceived by the local PME. The value of 65535 is returned when the PME is Down or Initializing.
This object maps to the aPMESNRMgn attribute in Clause 30.
If a Clause 45 MDIO Interface is present, then this object maps to the 10P/2B RX SNR margin register.
What is efmCuPmeSnrMgn?
This read-only value (in dB) reports the current signal-to-noise ratio margin as measured by the local PME on the received signal, with 65535 returned when the line is down or initializing. Admins watch this alongside efmCuPmeThreshSnrMgn to judge how close a copper line is to noise-related instability.
