What the steps of Port troubleshooting for Ruijie Switch?
1. Check the port status: show int stadata/attachment/forum/202306/27/115747r21mjuh9bjjxb2f2.png
2. Check whether the port type is correct(if switch has combo port, you are advised to check whether the cable connects to the right port)
If the port type is incorrect, you can use thiscommand:
Ruijie>enable
Ruijie#config t
Ruijie(config)#int gi 0/48
Ruijie(config-if)#medium-type fiber ---change the port type to fiber port
Ruijie(config-if)#medium-type copper --- change the port type to copper port
Ruijie(config-if)#end
Ruijie#write

Troubleshooting steps:
[*]Check the port status: show int sta
[*]Check whether the combo port (The switch is 4 fixed optical port, the check is ignored）
[*]Check the optical module information and optical power meter: show int tran; show int tran dia
[*]Put the optical module on the same type and normal switch to test, can up.
[*]Self-loop test.
