Switch#
This example shows how to display monitoring data for the transceivers on interface Gi1/2:
Switch# show interfaces g1/2 transceiver
ITU Channel 23 (1558.98 nm),
Transceiver is externally calibrated.
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).
