Network Management and Monitoring

  • HMC fatal error SNMP trap (QFX10002-36Q, QFX10002-60C, QFX10002-72Q, QFX10008, QFX10016, PTX1000, PTX10002-60C, PTX10008, and PTX10016)—Starting in Junos OS Release 22.3R1, the listed devices send SNMP trap messages from the SNMP agent to the SNMP manager whenever a Hybrid Memory Cube (HMC) fatal error occurs and gets cleared.

    We've added the following traps to detect the HMC fatal errors:

    • jnxASICExternalMemTraps and jnxASICExternalMemOKTraps at the jnxTraps hierarchy level. The jnxASICExternalMemTraps and jnxASICExternalMemOKTraps traps get triggered when there is an ASIC external memory error.

    • jnxHmcFatal at the jnxASICExternalMemTraps hierarchy. The jnxHmcFatal trap triggers when it detects that the specified HMC on a specific FPC has failed.

    • jnxHmcOK at the jnxASICExternalMemOKTraps hierarchy level. The jnxHmcOK trap triggers when the specified HMC on a specific FPC has recovered from the failure.

    The HMC SNMP traps are raised for fatal HMC errors only. The jnxHmcOK trap is triggered only once for each FPC, although several fatal HMC errors are triggered and then cleared.
