Hi,

 

Do you have a picture of the Cisco SFP that you have used on port 12?

 

What is the firmware/OS of your switch currently?

 

Can you try running this command on interface level, #speed 1000 to check if it helps. 

Dear @DELL-Joey C​ 

Unfortunately, I don’t have SFP Picture .  I will try to get it.

I tried to with #speed 1000 it not help me on this firmware / OS

Below is firmware / OS

OS Version: 10.5.2.7
Build Version: 10.5.2.7.374
Build Time: 2021-07-28T04:48:16+0000
System Type: S4128F-ON
Architecture: x86_64

Hi,

 

Can you please update the OS to 10.5.6.0, and you mentioned the command #speed 1000 did not help, did it give you an error or the media still shows 25G? Let us know more about the SFP when you manage to get a picture of it. 

@DELL-Joey C​ 

It,s not giving any error . To upgrade i need to take approval that will take time from managment.
