(from logs) >...%PHY-4-CHECK_SUM_FAILED: SFP EEPROM data check sum failed for SFP interface Gi1/0/28
Remove and reinsert the SFP. If you get the same error again in the same way, the SFP (for this port) may be defective
===> replace it with another one.
+ Check logs again afterwards to check if the problem has gone away or not

@marce1000I obtained a new Multi-Mode SFP module, connected it, and the switch functioned normally. Is there a way to temporarily use a faulty SFP module? Buying and receiving a new one will take time, and I need to deliver a project urgently."

- The switch can not be used with a faulty SFP module.
