System log messages to indicate checksum errors on the DDR3 interface

Two new system log messages, XMCHIP_CMERROR_DDRIF_INT_REG_CHKSUM_ERR_MINOR and XMCHIP_CMERROR_DDRIF_INT_REG_CHKSUM_ERR_MAJOR, are added to indicate memory-related problems on the interfaces to the double data rate type 3 (DDR3) memory. These error messages indicate that an FPC has detected a checksum error, which is causing packet drops. The following error threshold values classify the error as a major error or a minor error:

• Minor error- 6-254 errors per second
• Major error-255 and more errors per second
