Just tested DOM support on SXI. Here are the findings:

1) much more accurate static thresholds table for DOM-supported
   transceivers than in SXH4

- e.g. for XENPAK-ZR, SXH4 has strange temperature, TX Power & RX power
  static thresholds - which are now correct in SXI

2) laser current thresholds still "N/A" and the transceivers showing low
   alarm (--)  

                            High Alarm  High Warn  Low Warn   Low Alarm
            Current            Threshold   Threshold  Threshold  Threshold
Port        (milliamperes)     (mA)        (mA)       (mA)       (mA)
----------  -----------------  ----------  ---------  ---------  ---------
Te1/1       102.1         --     N/A        N/A        N/A       N/A

   This is working fine in SXF which reads manufacturer's thresholds from
   the transceiver:

                            High Alarm  High Warn  Low Warn   Low Alarm
         Current            Threshold   Threshold  Threshold  Threshold
Port     (milliamperes)     (mA)        (mA)       (mA)       (mA)
-------  -----------------  ----------  ---------  ---------  ---------
Te1/4    101.5               152.4       142.3        61.0       50.8


3) for SFPs with external calibration IOS has reversed or broken threshold
   violation comparisions. This is also working fine in SXF.

#sh inte transceiver threshold violations
Gi5/1       0000:00:32:15    0000:00:02:03         Tx power high alarm
                                                 -6.0 dBm >  -1.0 dBm
                          0000:00:02:03         Tx bias high alarm
                                                  4.0 mA >  14.9 mA


    With kind regards,

         M.
