alarmChromaticDispersionTooLow
Module: ADVA-FSPR7-MIB
OID (symbolic): ADVA-FSPR7-MIB::alarmChromaticDispersionTooLow
OID (numeric): 1.3.6.1.4.1.2544.1.11.7.5.0.295
Node type: NOTIFICATION-TYPE
Description:
Chromatic Dispersion too Low
What is alarmChromaticDispersionTooLow?
This notification is triggered when the chromatic dispersion measured on an optical link drops below acceptable thresholds, which can degrade signal quality. Chromatic dispersion is a fundamental optical phenomenon where different wavelengths travel at different speeds through fiber, and insufficient dispersion compensation can cause signal degradation. An operator monitoring optical transport systems would use this alarm to identify and correct dispersion compensation issues before they impact traffic.
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::alarmChromaticDispersionTooLow snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.2544.1.11.7.5.0.295
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
