Hi all,
I would like to seek for some advice on the issue that faced on uplink ports (TengigabitEthernet1/0/3) which the port will still remain up even I had unplugged the fiber cables (ping will lost). This port was having the exact same configuration on TengigabitEthernet1/0/4 as they are binding together as port-channel.
Hardware Model = SG350 & SG350X
Current Firmware = 2.5.5.47 (Latest) and have been testing with 2.5.0.92 unfortunately still facing same issue.
So far, I discovered that the issue was faced only on port TengigabitEthernet1/0/3 but TengigabitEthernet1/0/4 was not having any issue. Furthermore, I have around 20 units of same model and all was facing the same issue on port TengigabitEthernet1/0/3 with SFP of "MGBLX1".
Kindly need some advice on this abnormality and any solutions that I can take?
Thank you for your kind assistance.
