let me explain the topology , it is a simple one
i am connecting interface 1/0/1 using 1GB transceiver to a host with IP 172.16.16.155 .
interface 1/0/3 using 10GB transceiver to a host with IP 172.16.16.73 .
switch outputs:

001c-7f60-6465 1 Learned XGE1/0/3 Y
Mac : 001c-7f60-6465 is the mac address of host 172.16.16.73 which is behind the 10GB transceiver .
looks like the switch isn't able to deal with 1GB transceiver . (i tried so many 1GB transceivers with different manufactures)
