I bought an ASF-GE-T, 1.25G copper module. Now it’s used on the Cisco 3560cx switch, an error is reported. HomeSW# HomeSW# Jan 5 15:49:17.087: %PHY-4-SFP_NOT_SUPPORTED: The SFP in Gi1/0/15 is not supported Jan 5 15:49:17.087: %PM-4-ERR_DISABLE: gbic-inv

Solution:
1. Manually modify the port rate to 1G and test again.
2. Check the IOS version of the device.The customer feedback that the problem is solved after IOS upgraded.
