after reloading C9300 switch (version 17.6.4), interface te1/1/4 go to down state, and log display:

%SFF8472-3-READ_ERROR: Te1/1/4: Error reading DOM data from transceiver

if I unplug / plug cable in Te1/1/4, interface go back TO UP state. (it is not config probleme)

what is the SFP model is this DOM computable - show interface te1/1/4 tran (this is where you get this message).

other side may be BUG but we need to know SFP mode, on Cat 9300 never seen this issue.

Workaround: The only workaround known is to add the "speed nonegotiate" command in both sides of the link. After applying this command the interface will work correctly even after a reboot.

Look like you hitting BUG as per the information it was fixed in 17.6.4 (looks like it was not) contact TAC
