Some of them will not work.
The command is show interface transceiver. If the transceiver supports DOM, it will show something like this:
show interface transceiver
Transceiver monitoring is disabled for all interfaces.
If device is externally calibrated, only calibrated values are printed.
++ : high alarm, + : high warning, - : low warning, -- : low alarm.
NA or N/A: not applicable, Tx: transmit, Rx: receive.
mA: milliamperes, dBm: decibels (milliwatts).
