Dùng FortiGate 80F/81F mà sau khi nâng cấp lên firmware 7.4.8 bị mất kết nối qua cổng quang (SFP) (Open)

Nặc danh

thg 6 16, 2025

Chia sẻ lại case hôm trước. Vì sao mình bị chết sfp nhé

Hãng ngày càng bóp.

Anh em nào dùng FortiGate 80F/81F mà sau khi nâng cấp lên firmware 7.4.8 bị mất kết nối qua cổng quang (SFP) thì đọc cái này nhé!

Lý do là FortiOS mới bị lỗi nhận sai loại cổng, tự chuyển về copper, nên nếu đang cắm module quang là bị "mất mạng" luôn

Cách fix tạm thời:

Mở CLI và gõ:

diagnose hardware shared-port <port> fiber
