Hi Naveen,

%PHY-4-CHECK_SUM_FAILED:

SFP EEPROM data check sum failed for SFP interface [chars]

The SFP was identified as a Cisco SFP, but the system was unable to readvendor-data information to verify its correctness.

Recommended Action: Remove and reinsert the SFP. If it fails again in the same way, the SFP may be defective.

Regards,

Dan
