Hi Asri,

The best way i know is to enter this command:

show idprom interface gigabitEthernet 1/0/35

Just replace the port number with your own target.

Hello asri-putri ,

To check the SFP module on a Cisco device, you can use the "show interfaces transceiver" command. This command provides detailed information about the SFP module, including its type, status, and various optical parameters such as temperature, voltage, and power levels.

show int t5/1 transceiver detail

ITU Channel not available (Wavelength not available),
Transceiver is internally calibrated.
mA: milliamperes, dBm: decibels (milliwatts), NA or N/A: not applicable.
++ : high alarm, + : high warning, - : low warning, -- : low alarm.
A2D readouts (if they differ), are reported in parentheses.
The threshold values are calibrated.

High Alarm High Warn Low Warn Low Alarm
Temperature Threshold Threshold Threshold Threshold

--------- ------------------ ---------- --------- --------- ---------
Te5/1 31.6 75.0 70.0 0.0 -5.0
