ifBERTDownMargin

Module: PDN-DIAGNOSTICS-MIB

OID (symbolic): PDN-DIAGNOSTICS-MIB::ifBERTDownMargin

OID (numeric): 1.3.6.1.4.1.1795.2.24.2.16.1.1.2.1.16

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This represents the Downstream margin in decibels (DB).

What is ifBERTDownMargin?

The downstream noise margin, in decibels, measured during the BERT test; a low margin (a few dB) suggests the downstream signal is close to the noise floor and prone to future error bursts even if the line currently syncs fine.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1795.2.24.2.16.1.1.2.1.16
snmpwalk -v2c -c public <target> PDN-DIAGNOSTICS-MIB::ifBERTDownMargin

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.1795.2.24.2.16.1.1.2.1.16.1
snmpget -v2c -c public <target> PDN-DIAGNOSTICS-MIB::ifBERTDownMargin.1
