Catalyst 6500 with Sup 720 appear error msg about fabric channel

Dear Sir

My Cat 6513 with Sup 720 appear error msg

Jul 31 17:02:22.981: SP: Fabric endpoint of Channel 3 lost Sync. to Lower fabric and trying to recover now!

Jul 31 17:12:55.123: SP: Linecard endpoint of Channel 3 lost Sync. to Lower fabric and trying to recover now!

I have no idea about this error but no any problems or any complain from users. So, I have no idea that this error is just warning or critical error. Anyone, who know about this error, please give me some advise.

Thank you very much.

Wisit

show fabric errors >> see if there are kind of errors.

show fabric channel-counters >> see if there are kind of errors.

sho fabric fpoe map >> To see which line card is mapped to channel 3.

If you see errors from show fabric error and channel-counters and it maps to the slot number on fpoe map. Suggestion is to re-seat that line card, it might not be seated properly or the line card channel is stuck hence losing sync with the fabric. Once the card is reseated please check "sh diag all" for any failures.

Please rate this post if it helps.
