Finally, saw the can0 line with ifconfig command after all those steps:

echo 2 \> /sys/class/gpio/export  
echo out \> /sys/class/gpio/gpio2/direction  
echo 1 \> /sys/class/gpio/gpio2/value

// Enable level shifter on the CAN IoT card  
echo 13 \> /sys/class/gpio/export  
echo out \> /sys/class/gpio/gpio13/direction  
echo 1 \> /sys/class/gpio/gpio13/value

modprobe can  
modprobe can-dev  
modprobe can-raw  
modprobe mcp251x  
ip link set can0 type can bitrate 125000 triple-sampling on  
ifconfig can0 up

**And after restarting MangOH red board I can not get it up and running again, why?**  
cannot find device “can0”
