atmfM4HwPIUnitMismatchAlarm

Module: ATM-FORUM-SNMP-M4-MIB

OID (symbolic): ATM-FORUM-SNMP-M4-MIB::atmfM4HwPIUnitMismatchAlarm

OID (numeric): 1.3.6.1.4.1.353.5.1.3.1.2.0.31

Node type: NOTIFICATION-TYPE

Description: Indicates that a plug-in unit type mismatch 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 atmfM4HwPIUnitMismatchAlarm?

This SNMP trap (notification) is sent when a plug-in hardware unit in an ATM network element is inserted but is of the wrong type or is incompatible with the slot. An operator would receive this alarm when they install incorrect hardware or when the system detects a hardware mismatch condition. This helps alert network administrators to installation errors that could prevent proper system operation.

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::atmfM4HwPIUnitMismatchAlarm
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.353.5.1.3.1.2.0.31

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:
