Module: CYAN-MIB

Description:
LOOPBACK
What is cyanAlarmLoopback?
This notification indicates a loopback condition was detected on an optical device. It signals that traffic is being routed back to the source instead of egressing normally. An operator receives this alert to identify and clear the loopback before it disrupts service.
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> '' CYAN-MIB::cyanAlarmLoopback snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.28533.5.20.30.99
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:
