I have a JunOS v15.1 EX4200 that I have setup with SNMP traps. One of the traps I have received is for DOM alarms. The text I get returned is as follows: "Notification of a recently set Dom alarm. ifDescr=ge-1/1/0 DomLastAlarms=00 00 00 DomCurrentAlarms=08 00 00 DomCurrentAlarmDate=07 E2 02 1B 0A 20 11 00 2D 05 00". I have found via the MIB files that the format of the alarms variable is based on the JnxDomAlarmId type, which is as follows:
JnxDomAlarmId ::= TEXTUAL-CONVENTION
STATUS current
DESCRIPTION
"Identifies specific DOM alarms that may exist on an
interface."

My question - how do I interpret "DomCurrentAlarms=08 00 00" and get the correct alarm that it represents, which I think is "Laser rx power low alarm (4)". I have tried a few differnet ways, but I never seem to get the result that "show interfaces diagnostics optics ge-1/1/0" gives:
