cyanAlarmTpLop
Module: CYAN-MIB
OID (symbolic): CYAN-MIB::cyanAlarmTpLop
OID (numeric): 1.3.6.1.4.1.28533.5.20.30.91
Node type: NOTIFICATION-TYPE
Description: TP_LOP
What is cyanAlarmTpLop?
This OID triggers a network alarm notification when a Transmission Path Loss of Pointer (TP_LOP) condition is detected on an optical link. Operationally, this indicates the optical receiver has lost synchronization with the incoming signal—a critical failure in optical transmission. A network operator would be alerted by this alarm when an optical port stops receiving valid signal, requiring immediate investigation of fiber connectivity or transceiver health.
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::cyanAlarmTpLop snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.28533.5.20.30.91
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:
zoo11-linux.zoo [UDP: [192.168.30.111]:65081->[192.168.30.10]:162]: DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (372570681) 43 days, 2:55:06.81 SNMPv2-MIB::snmpTrapOID.0 = OID: CYAN-MIB::cyanAlarmTpLop
