atmfM4HwPIUnitProbAlarm

Module: ATM-FORUM-SNMP-M4-MIB

OID (symbolic): ATM-FORUM-SNMP-M4-MIB::atmfM4HwPIUnitProbAlarm

OID (numeric): 1.3.6.1.4.1.353.5.1.3.1.2.0.30

Node type: NOTIFICATION-TYPE

Description: Indicates that a plug-in unit problem condition has occurred on the hardware unit associated with the specified index.

An entPhysicalClass of unknown(2) along with both an entPhysicalContainedIn of 0 and an entPhysicalParentRelPos of -1 indicates that the error occurred in the ATM NE but not in any one hardware unit maintained in the MIB table.

What is atmfM4HwPIUnitProbAlarm?

This notification alerts management systems when a plug-in unit (hardware module) experiences an error condition in an ATM network element. The alarm indicates a hardware problem but may lack granular details if the error occurred in an unidentified physical unit. Network monitoring systems use this to trigger alerts for maintenance when hardware faults develop.

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> '' ATM-FORUM-SNMP-M4-MIB::atmfM4HwPIUnitProbAlarm
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.353.5.1.3.1.2.0.30

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:
