ifPerfFecQMargin
Module: LUM-IFPERF-MIB
OID (symbolic): LUM-IFPERF-MIB::ifPerfFecQMargin
OID (numeric): 1.3.6.1.4.1.8708.2.56.2.3.1.1.12
Node type: OBJECT-TYPE
Type: Unsigned32WithNA
Access: read-only
Description: Q factor margin (dB) with respect to the FEC threshold.
What is ifPerfFecQMargin?
The Q-factor margin in dB relative to the FEC decision threshold; a higher margin means more headroom before errors become uncorrectable, so an admin uses it as an early-warning indicator of link quality degrading toward the FEC limit.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.8708.2.56.2.3.1.1.12 snmpwalk -v2c -c public <target> LUM-IFPERF-MIB::ifPerfFecQMargin
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.8708.2.56.2.3.1.1.12.1 snmpget -v2c -c public <target> LUM-IFPERF-MIB::ifPerfFecQMargin.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ifPerfFecQMargin.1
