OID (numeric): 1.3.6.1.4.1.629.200.13.0.32
Node type: NOTIFICATION-TYPE

Sent when bias current is too small. For SFF Digital Diagnostics, this corresponds to the low bias current alarm.
This Notification should be of Severity ERROR.
What is nbsCmmcTrapPortAmpsTooLow?
This trap fires when the laser module's bias current—critical for maintaining signal quality—drops below acceptable operating limits. For SFF (Small Form Factor) transceivers with digital diagnostics, this specifically indicates a low bias current alarm that could degrade optical transmission. Network operators must investigate and correct the bias current to prevent signal loss or transceivers shutting down.
Examples
Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):
snmptrap -v2c -c public <manager> '' NBS-CMMC-MIB::nbsCmmcTrapPortAmpsTooLow snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.629.200.13.0.32
Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):
snmptrapd -f -Lo -c /dev/null authCommunity log public
