Vx/Hdx/Mx Router SNMP Traps
• Low TX Bias Alarm Begin and Clear
A SFP module has the ability to monitor and alarm on a high or low TX bias current reading. This
ability is internal to the SFP and is part of the digital diagnostic interface common to many SFPs.
This notification is sent when bit 2 of byte 112 in the real-time diagnostic registers changes from 0
to 1 (Begin) or from a 1 to a 0 (Clear).
This bit is set when the internal current to the SFP transmitter falls below the low current alarm
level. The SFP TX BIAS current value is stored at bytes 100 & 101 of the SFP diagnostic register
table.

• High TX Power Alarm Begin and Clear
A SFP module has the ability to monitor and alarm on a high or low TX laser power reading. This
ability is internal to the SFP and is part of the digital diagnostic interface common to many SFPs.
This notification is sent when bit 1 of byte 112 in the real-time diagnostic registers changes from 0
to 1 (Begin) or from a 1 to a 0 (Clear).
This bit is set when the SFP transmitter laser power exceeds the high power alarm level. The
SFP TX power value is stored at bytes 102 & 103 of the SFP diagnostic register table.
