i have a problem with the C9300 switch uplink

[dion-winandar]

On port te1/1/1 I have a problem where the LED indicator on the port is always alternating green and orange, and because of that the internet network at that location is unstable and I checked the log on the switch and I didn't find any logs related to the interface, can you help me?

Ooops.  Wrong command.

What is the far end of this fibre?  

What is the distance of the far end device?

[dion-winandar]

it goes to the core switch on the server, and the distance is about 500m

[Leo Laohoo]

From this "core switch", post the complete output to the command "sh interface <PORT> transceiver detail".

[dion-winandar]

ok i will try but maybe i will do open tac, thanks for your help

The alternating green and orange LED on port te1/1/1 of your C9300 switch suggests a link issue. Check the cable, reseat it, or try a new one. Ensure speed and duplex settings match the connected device. Review interface statistics using show interface te1/1/1 for errors and verify spanning tree status with show spanning-tree.The alternating green and orange LED on port te1/1/1 of your C9300 switch suggests a link issue.

[dion-winandar]

but previously it worked safely without any problems
