Issue:
When a link down trap is sent to Spectrum the device shows a link down trap has been received, but no alarm is generated on the port even though generateportstatusalarms and alarmonlinkdowntrap are both true.
Cause:
This is due to trap exploders interpretation of ifindex values that are higher than 301989887.  If you are not using trap exploder, you will not experience this problem. 
Resolution:
This is resolved in Spectrum_10.03.00.BMP_10.3.001 for 10.3.0  This will be resolved in CA Spectrum 10.3.1 once released. 

    Symptom: Link down alarm are not processed correctly on interfaces from TrapX when Object instance ID is very large.
    Resolution: Link down alarms are processed correctly from TrapX even Object instance ID is very large.
