Examples
This example shows how to display diagnostic monitoring data for all interfaces with transceivers
installed on the switch:
Switch# show interfaces transceiver
Switch#
Note
This example shows how to display detailed diagnostic monitoring data, including calibrated values,
alarm and warning thresholds, A2D readouts, and alarm and warning flags. The A2D readouts are
reported separately in parentheses only if they differ from the calibrated values:

If device is externally calibrated, only calibrated values are printed.
++ : high alarm, + : high warning, -
NA or N/A: not applicable, Tx: transmit, Rx: receive.
mA: milliamperes, dBm: decibels (milliwatts).

The value for Optical Tx Power (in dBm) equals ten times log (Tx Power in mW). If the Tx
Power value is 3 mW, then the Optical Tx Power value equals 10 * log (3), which equals 10 *
.477 or 4.77 dBm. The Optical Rx Power value behaves similarly. If Tx Power or Rx Power is
zero, then its dBm value is undefined and is shown as N/A (not applicable).
mA: milliamperes, dBm: decibels (milliwatts), NA or N/A: not applicable.
++ : high alarm, + : high warning, -
A2D readouts (if they differ), are reported in parentheses.
The threshold values are calibrated.
