This example shows how to display the monitoring data for the interfaces that have transceivers installed
on module 2:
Switch# show interfaces transceiver module 2
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).
