SFF8472-5-THRESHOLD_VIOLATION trong syslog

24-06-2015, 09:21 AM

Chào tất cả mọi người,

Mình gặp thông báo trong syslog giống dưới, tham khảo ở link của cisco thì nói là lỗi tín hiệu quang giữa 2 thiết bị, nhưng không hiểu sao nó chỉ thông báo lỗi này trong khoảng thời gian gian ban đêm (từ 23:00 đến 6:30 sáng) thôi . còn ban ngày (trong giờ làm việc) thì không có thông báo trên syslog.

Mong được diễn đàn chia sẽ và tìm hướng giải quyết giúp.

Xin cám ơn.

có thể có nhiều nguyên nhân.

1/ Đây có thể là cisco bugs - lỗi của hệ điều hành. Em có thể cân nhắc để nâng cấp switch lên phiên bản IOS mới hơn.

2/ Thử tháo ra và gắn lại transceiver, fiber connector. Nếu có điều kiện thì đổi sang transceiver khác.
