%PHY-4-SFP_NOT_SUPPORTED: The SFP in (PortNo#) is not Supported  - Cisco Catalyst 2960 X Series (WS-C2960X-48TS-LL)

I am trying to add a non cisco SFP between two catalysts, and am getting the error %PHY-4-SFP_NOT_SUPPORTED: The SFP in (PortNo#) is not Supported.

I have tried running the commands:

Switch(config)#service internal
Switch(config)#no errdisable detect cause gbic-invalid
Switch(config)#service unsupported-transceiver
Switch(config)#int gi0/49
Switch(config-if)#no shutdown
Switch(config-if)#do copy run start

However, the issue is still occurring. I have rebooted the switch after the above with no joy. Cable being used is a StarTech 3m SFP+ 10-Gigabit Ethernet (10Gbe) Twinax Cable. I will be upgrading the firmware to 15.2.6 while waiting for a reply.

Any help will be appreciated.

I research, I found the below results :
Your switch support SFP not SFP+
You plugged  SFP 10 in 1 gig slot which is incompatible
The upgrading won't help you.
Solution :
Try a compatible  SFP 1 gig
