nbsSigCondPortReflection
Module: NBS-SIGCOND-MIB
OID (symbolic): NBS-SIGCOND-MIB::nbsSigCondPortReflection
OID (numeric): 1.3.6.1.4.1.629.227.100.2.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Measured back reflection power, in millidecibels (mdBm). User interfaces should show this in decibels (dBm). Not supported value: -100000
What is nbsSigCondPortReflection?
This read-only counter reports the measured optical power reflected back into this port, in millidecibels relative to 1mW, shown as dBm in UIs. Elevated back reflection usually indicates a poor connector mate or fiber break and can destabilize lasers or degrade signal quality upstream, so admins monitor this alongside rx/tx power. A jump in reflected power on a given port right after a patch-panel change points to a dirty or improperly seated connector that needs cleaning or reseating.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.629.227.100.2.1.4 snmpwalk -v2c -c public <target> NBS-SIGCOND-MIB::nbsSigCondPortReflection
Get a specific instance (index 1):
