Symptom
When 40G SFP is inserted and 'show interface transciever' CLI command is given, no output will be shown.
Example:
switch#show int te1/1/1 transceiver
Diagnostic Monitoring is not implemented.
switch#show int te1/1/1 status
Port Name Status Vlan Duplex Speed Type
Te1/1/1 connected 1 full 10G QSFP 40G SR4 SFP
Conditions
40G SFP has to be inserted in the SFP container location on switch and CLI command has to be given to derive Bias Current, Temperature, Rx Power and Tx Power values.
Further Problem Description
Dom supported SFPs need to show the sensor read values for the Bias Current, Temperature, Rx Power and Tx Power sensors that are in the 40G SFPs.
Please make sure that used transceiver supports DOM.
