Trap Service and Functions
All ION system SNMP Trap messages conform to SNMPv2 MIB RFC-2573.
See the “
Supported MIBs
” section on page

for information on the x4120s support for public (standard)
and private MIBs. For information on “
Configuring SNMP
” see page

. See the
ION Management Mod-
ule (IONMM) User Guide
manual for SNMP traps supported on the IONMM.
A sample SNMP Message sequence is shown below.
Figure 3: SNMP Message Sequence
The ION x4120 supports a Trap function to report the status as follow:
1) Ports link status change:
•
C4120 will send link up trap only once if port link status changes from link down to up;
•
C4120 will send link down trap only once if port link status changes from link up to down.
2) DMI trap:
•
An
ionDMIRxIntrusionEvt
event is sent if the
ionDMIRxPowerLevel
falls below the
ionDMIRxPwrLvlPreset
indicating an intrusion on the fiber
•
ionDMIRxPowerEvt
event is sent when there is a warning or alarm on Rx Power
•
ionDMITxPowerEvt
event is sent when there is a warning or alarm on Tx Power
•
ionDMITxBiasEvt
event is sent when there is a warning or alarm on Tx Bias current
•
ionDMITemperatureEvt
event is sent when there is a warning or alarm on DMI temperature.
•
C4120 will keep sending DMI traps until it becomes normal. Like the other ION SICS, the
C4120 will periodically send out the specific trap every 3 seconds until the trap event
condition doesn’t meet.
