I have used below commands but status is still same.
TOR-05# configure terminal
TOR-05(config)# allow unsupported-transceiver
TOR-05(config)# unlock third-party transceiver

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.

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.
