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

Admin

thg 3 26, 2026

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
