alarmLossOfFrameMux
Module: ADVA-FSPR7-MIB
OID (symbolic): ADVA-FSPR7-MIB::alarmLossOfFrameMux
OID (numeric): 1.3.6.1.4.1.2544.1.11.7.5.0.176
Node type: NOTIFICATION-TYPE
Description: Multiplexer Loss of Frame
What is alarmLossOfFrameMux?
This SNMP notification (trap) is triggered when the multiplexer in an Adva optical transport system loses frame synchronization, meaning it cannot properly extract timing or structure from the incoming optical signal. Loss of Frame is a critical fault that halts data transmission through the multiplexer, so this alarm alerts operators immediately to degraded optical signal quality or equipment failure. Operators use this alert to diagnose optical signal problems and initiate failover to backup circuits.
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::alarmLossOfFrameMux snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.2544.1.11.7.5.0.176
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:
