What is cyanAlarmPacketLpbk?
This is an alarm notification triggered when packet loopback testing detects a problem. It signals that a diagnostics packet sent out returned when it shouldn't have, indicating a loop. An operator receives this alert when network gear mistakenly forwards packets back to the source instead of to customers.
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::cyanAlarmPacketLpbk snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.28533.5.20.30.104
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
