alarmLossOfMultiFrameOtu
Module: ADVA-FSPR7-MIB
OID (symbolic): ADVA-FSPR7-MIB::alarmLossOfMultiFrameOtu
OID (numeric): 1.3.6.1.4.1.2544.1.11.7.5.0.182
Node type: NOTIFICATION-TYPE
Description: OTU LOM
What is alarmLossOfMultiFrameOtu?
This SNMP trap notification indicates that the Optical Transport Unit (OTU) has lost multiframe synchronization, a critical error condition in optical transmission. When an OTU loses multiframe alignment, it cannot properly demultiplex payload data, disrupting the entire optical signal. Network operators monitor this alarm to detect optical link degradation and trigger immediate troubleshooting or failover actions.
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> '' ADVA-FSPR7-MIB::alarmLossOfMultiFrameOtu snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.2544.1.11.7.5.0.182
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
Example snmptrapd log entry:
