Description:
Sent when SingleFiber port no longer detects its own signal returning.
This Notification should be of Severity WARNING.
What is nbsCmmcTrapPortReflectionCeased?
This notification is sent when a single-fiber optical port stops detecting its own transmitted signal reflecting back from the remote end, indicating fiber break, connector disconnect, or transceiver failure on that port. The trap includes details about which port and which system the alert originated from. An operator would receive this alarm to immediately detect fiber link failures, triggering investigation and replacement of failed fiber segments or modules.
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> '' NBS-CMMC-MIB::nbsCmmcTrapPortReflectionCeased snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.629.200.13.0.46
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
